Brandi Glanville & Joyce Giraud Sorry, Gaga ... We're Too Busy To Be In Your Video

The "Real Housewives of Beverly Hills" did a cameo in Lady Gaga's new music video -- but two prominent cast members are missing ... and it was NOT Gaga's decision to keep them out ... the women opted out themselves.

Brandi Glanville and Joyce Giraud are conspicuously absent from the video, "G.U.Y." ... and rumors swirled they had been banned by Mother Monster herself.

But sources close to the shoot tell TMZ the rumors aren't true -- Gaga wanted the ENTIRE cast for the shoot ... but Joyce and Brandi took a pass because they had previous commitments.

Gaga's rep confirms to us she extended the invite to the entire cast.

The music video is bizarre ... with images of Michael Jackson, Jesus, Gandhi and Lady G as a feathery bird-woman. But when the Housewives show up -- pretending to play musical instruments -- it's classic over-the-top Gaga.

Shaquille O'Neal Under Investigation Allegedly Punched Man at TV Studio

Shaquille O'Neal is under investigation by Atlanta Police ... after a man claims the ex-NBA star punched him at Turner studios last year ... though Shaq claims the two were simply horsing around.

Jennifer Tilly 76% Of My Celeb Friends Are Cheating Horndogs

0-ef5zrspj

Jennifer Tilly says most of her Hollywood friends are philanderers ... but adds the situation isn't as dire as Cameron Diaz thinks.

We got Jennifer last night -- sans poker-playing long-time partner Phil Laak -- and asked her what she thought of Cameron's observation ... everyone will be cheated on at some point in their life.

Jennifer says it's definitely more likely than not ... but sets the percentage at less than 100.

Like the joke goes ... you're only as faithful as your options.

White House Pastry Chef I Didn't Butter Up Obama

0-6etn0c2b

White House Executive Pastry Chef Bill Yosses admits ... it looks pretty incriminating -- carrying his luggage on the streets of D.C. after announcing he's quitting.

Our photog Colin did a masterful job -- we think -- getting the downlow on the resignation. Bill shoots down rumors he butted heads with Michelle Obama over sugary and buttery desserts -- he says they were more like partners in crime.

Bill doesn't seem to think you need butter and sugar for deliciousness ... Hmmm.

Bill's official reason for resigning in June -- he wants to spend more time with his husband in NYC .

Good job, Colin.

Karrueche Tran I Dumped Chris Brown Because He's a Man Whore

Karrueche Tran didn't dump Chris Brown because of the girl he allegedly banged in rehab -- sources close to the model tell TMZ ... she dropped the hammer on their relationship because he refused to stop texting his army of jump offs.

There's been speculation that Karrueche pulled the plug when she found out he had hooked up with another girl in his facility at the beginning of March -- but we're told the break-up preceded that ... We're told Karrueche ended things after she visited Chris in rehab the month before.

Sources tell us ... Karrueche saw Chris' phone during her visit -- and it was filled with inappropriate texts from other girls. It was the last straw. We're told Karrueche was especially pissed because she'd been nothing but supportive to Chris throughout his ordeal, even going to court with him.

We're told Karrueche wasn't even aware Chris had allegedly been getting down with girls in rehab until long after the break-up.

Lance Bass There Has DEFINITELY Been a Gay President

0-33w4vffy

Lance Bass isn't sure if he'll see a gay president in his lifetime, but he thinks there has definitely been a little same-sex lovin' in the Oval Office at some point.

Our photog caught up with Bass after his gig judging the Queen of the Universe Pageant and asked him the stereotypical gay-themed question (memo to photogs: Lance can talk about other things).

But the always-entertaining Bass made it fun ... saying the odds are at some time in history "someone in the White House has slept with the same sex."

He then jokingly added, "I'm looking at you, Roosevelt." Which raises the question ...

MJ's Chimp Bubbles Jane Goodall's LYING No One Spanked the Monkey

Just like her beloved chimpanzees ... Jane Goodall is throwing crap at the wall -- at least that's the word from people who witnessed Michael Jackson's relationship with Bubbles.

Several people who were with Bubbles on almost a day-to-day basis tell TMZ ... MJ adored the chimp, and treated him like a member of his family -- and the notion that he or anyone around him brutalized the chimp is garbage.

We're told the Michael Jackson Estate has recognized how much the singer loved Bubbles by contributing money to the sanctuary where the chimp now lives.

Bubbles, we're told, was almost joined at the hip with Michael, mimicking him and various others at Neverland. We were told one story where Bubbles got down on his knees after seeing one of the maids and started dusting the floor. The whole slave labor thing aside, Michael proudly hugged the chimp.

And Michael actually made Bubble's his plus one at his lawyer John Branca's wedding. Bubbles showed up in a tux to cheer on Branca -- who now runs the MJ Estate.

Floyd Mayweather Accusers The Cracked Bones [Photos]

A broken arm ... a snapped pinkie ... and evidence of extreme torture -- just a few of the injuries suffered by one of the men allegedly beaten by Floyd Mayweather's crew ... and TMZ Sports has the X-rays.

We broke the story ... two men have lawyered up, claiming Mayweather ordered them to be beaten to a pulp recently because he suspected they stole jewelry from his Vegas home.

One of the victims had X-rays taken after the alleged incident and they show a variety of painful injuries, including:

-- Broken right pinkie
-- Severe swelling of the left hand
-- Broken left ulna
-- Cracked right ulna
-- Multiple fractures in left hand that required pins to reset the bones

We're told the left arm was so badly broken, doctors drilled into the bone to attach a titanium plate so it would reset.

The men claim Mayweather was present during the attack, but it's unclear if the boxing champ actually participated in the beating.

For their part, we're told the men adamantly deny they took anything from Mayweather.

Chimp Expert Jane Goodall Bubbles Was Beaten On MJ's Watch

0-jza68mai

The world's leading chimp expert says Michael Jackson's famous pet monkey Bubbles was brutalized at Neverland and she blames MJ.

Jane Goodall dropped the bombshell leaving an event in Washington, D.C. ... saying Bubbles was BEATEN while in Michael's care. She doesn't say who beat Bubbles, but she does say she confronted MJ and it "ticked him off."

Our photog was clearly caught off guard and didn't ask the circumstances surrounding the alleged beating. La Toya's ex-husband, Jack Gordon, claimed the singer did indeed abuse Bubbles, saying, "I saw Michael punch Bubbles, kick him in the stomach. Michael used to say, 'He doesn't feel it. He's a chimpanzee. I have to discipline him.'"

Various people in the MJ camp denied the claims, and there are stories that Bubbles was actually treated like a hairy king, eating at the dining room table with MJ and having free access to the fridge for Haagen-Dazs fixes.

FYI -- Bubbles -- now 30 -- is alive and well ... living in a Florida animal sanctuary.

Mike Vick Huge Props from Philly Politician ... He's No T.O.

0-5mid45h1

Don't count out Michael Vick just yet -- the guy could still be a STARTER in the NFL, so says the former Governor of Pennsylvania ... who says he wishes Vick well after his stint in Philly.

FYI -- Vick is a free agent and there's rumors that he's accepted the fact he might have to resign himself to being a backup if he wants to keep playing in the league.

But ex-Gov. Ed Rendell is taking issue with that ... telling us the guy could still be the #1 for a handful of teams including the Jets, Raiders and Vikings.

His sports knowledge is actually pretty damn impressive for a politician (especially when he starts talking about the 76ers).

Terrell Owens should take note -- not every ex-Eagle gets run out of town.

MJ's Alleged Son "Dad" Speaks Out He Warned Me About DNA Lies

A man has come forward claiming he's the real father of 31-year-old Brandon Howard -- NOT Michael Jackson -- telling TMZ, Howard warned him earlier this week the DNA story would be breaking ... and told him it was phony baloney.

65-year-old Augie Johnson tells us, he fathered Brandon during his relationship with Brandon's mom, Miki Howard in the 80s -- and has remained a central figure in Brandon's life.

He tells us, he was in the delivery room when Brandon was born and even brought Brandon to recording studios as a child. We've seen multiple family photos of them together.

Augie says they're so close ... Brandon called him days before TMZ broke the story about the DNA test, telling him, "Don't worry about this stuff. You are my dad."

Augie insists his son had nothing to do with the DNA stunt -- telling us the "greedy people" around Brandon are the masterminds.

As for Brandon resembling MJ -- Augie says it's purely a coincidence. If anything, Brandon resembles Michael AFTER surgery -- so there's actually no resemblance at all.

'Mean Girls' Reunion Is Happening

Lindsay Lohan wasn't spewing BS on "Jimmy Fallon" Thursday night -- talking about a "Mean Girls" reunion -- TMZ has learned, it's been in the works for weeks.

FYI, 2014 is the 10th anniversary of the film's release -- and sources tell us, co-writer Tina Fey has been leading the charge for a reunion to commemorate the occasion ... wrangling the entire cast over the last month.

And Lindsay was apparently the last to know about it -- she went on "Fallon" Thursday talking about how she had just run into Tina who mentioned the reunion idea to her ... and Lindsay was into it.

It's unclear how the reunion will come together -- Jimmy suggested hosting it on his show -- but we're told it could also materialize as a comedy sketch ... maybe on an awards show.

Sources close to Tina tell us, several prominent cast members are already on board -- Amy Poehler (Mrs. George), Jonathan Bennett (dreamy Aaron), Rajiv Surendra (Math Enthusiast / Bad-Ass MC), and Daniel Franzese (Too Gay to Function).

Pretty awesome. Now get in losers. We're going shopping.

Rick Ross No Retaliation For 50 Cent Diss He Doesn't Deserve A Response

50 Cent may have been hoping to start a blood feud when he publicly insinuated Rick Ross and Diddy were gay lovers ... but sources close to Ross tell us there will be NO reprisals.

Sources tell us Ross won't retaliate for one simple reason -- he doesn't give a crap about 50 Cent or anything he says -- he thinks 50 is IRRELEVANT.

50 briefly posted a pic on Instagram Sunday showing Ross leaning in close to Diddy as if they're about to kiss ... with a caption that said, 'something ain't right' -- with the clear implication the rappers are gay.

We're told Rick plans to let it slide ... he wants to focus on making hit records ... and not on a childish beef with an old enemy.

50 Cent Retreats After Suggesting Diddy & Rick Ross Are Gay Lovers

50 Cent raised the stakes in his beef with 3 rap heavyweights -- publicly insinuating Diddy, Rick Ross and former record exec Steve Stoute are gay together ... but he backed down minutes later.

The shots were fired Sunday -- Fiddy posted the 2 pics on Instagram, one showing a pink-shirted Stoute embracing a pink-shirted Diddy. The other shows Diddy and Rick Ross from an angle that makes it look like they're kissing.

Underneath, 50 wrote the caption, "I ain't saying nothing, but something ain't right. Lmao." He yanked the pics down a short time later.

The photos were the latest in 50's ongoing feuds with the rap titans -- Stoute recently appeared in a VH1 documentary about hip hop, in which he called 50 a has-been. 50's been feuding with Rick Ross and Diddy for years.

As for why he pulled the post ... 50 probably thought twice about starting a nuclear war.

The Game Rapped About Banging Kim Kardashian I Also Hit It First

0-rn2i79kd

The Game didn't outright say he boinked Kim Kardashian back in the day ... but he did rap about it on a song with Ray J called, "I HIT IT FIRST"

TMZ obtained an early demo of Ray J's infamous song ... turns out Game was originally featured on the track -- and it sounds like he's rapping about hooking up with Kim.

Game is cryptic with his XXX lyrics -- but makes reference to her store "Dash" ... and says he'll show people how to really "drive that ghost" (seemingly talking about Kim's Rolls Royce Ghost.)

He also raps about getting oral sex from someone in a private jet.

All signs definitely point to sex.

Robin Thicke 'I'm Just Trying to Get Her Back'

0-fvhr8rpo

Robin Thicke was shockingly candid as he arrived in Washington D.C. Thursday afternoon ... making it clear he's not throwing in the towel on his marriage, telling our photog, "I'm just trying to get her back."

TMZ broke the story ... Paula Patton called him last Friday and said their marriage was over, and Robin flew to Canada -- where she was filming -- in a desperate but failed attempt to change her mind.

As we reported ... things really fell apart after Robin simulated sex with Miley Cyrus onstage at the VMAs last month. But Robin told our photog, the performance had nothing to do with his marital problems.

Our sources say Paula was livid and felt "utterly disrespected" by Robin's antics with Miley.

Robin is in D.C. for a concert Thursday night. He says his performance will be the same, even though some of his songs are about Paula.

He told our photog he's just trying to figure things out.
