Hook Ups

Floyd Mayweather is reeling tonight ... because he was on FaceTime with one of his best friends when the guy pulled out a gun, shot his wife and then killed himself ... TMZ has learned.

Sources tell us ... rapper Earl Hayes called Floyd on FaceTime Monday morning in a rage, over claims his wife -- VH1 star Stephanie Moseley -- had been unfaithful.

According to our Floyd sources, Earl said he was going to kill his wife. The champ was pleading with him to get a grip ... to no avail. Floyd will not say how much he saw, but he acknowledges he was a witness and heard everything.

Miley Cyrus has gotten a bad rap, allegedly corrupting her new BF Patrick Schwarzenegger, but we've learned he's an insane partier who is actually pushing her beyond her limits.

Celebs who have partied with both Miley and Patrick tell TMZ ... Patrick has been raging in Miami, organizing nightclub and strip club trips with his girlfriend and others ... and never seems to even take time to sleep.

Patrick -- who is well-known on the EDM circuit -- was at a Miami strip club with Miley and Paris Hilton, pulling out wads of cash and making it rain.

Pictures have surfaced of Patrick smoking weed with Miley and Wiz Khalifa. As one celeb source told us ... "He was smoking weed long before he met her [Miley]."

Ryan Seacrest has broken up with his girlfriend -- so we've learned -- and is out on the town with a new, attractive blonde chick.

Ryan was leaving the GQ Men of the Year party Thursday night at the Chateau Marmont in West Hollywood and his GF of more than a year-and-a-half, Shayna Terese Taylor, was nowhere in sight. That's because we're told Seacrest said bye bye.

Taylor Swift and Victoria's Secret model Karlie Kloss totally made out at a concert Thursday ... or maybe not. Who knows?

The ladies were rocking out at indie rock band The 1975's show in NYC when they moved in really, really close to each other's faces. Naturally, everyone wants to believe 2 hot chicks are sucking face.

It's hard to tell from pics and video if it's really a kiss or not -- but we know which answer we'd prefer, naturally.

Christina Milian has been tight-lipped about her possible relationship with Lil Wayne, but she did let a few things slip when we asked her about the holidays.

Milian was out to dinner Wednesday at Boa Steakhouse with Karrueche Tran when we brought up Weezy's crazy gift-giving skills ... and asked what Christina was expecting under the tree this year?

Watch the video for her answer -- or watch just to see Karrueche and Christina ... who had a near nip-slip.

PAY ATTENTION FELLAS ... Super hot UFC superstar Ronda Rousey is about to give you some incredibly valuable information ... about what NOT to do if you ever wanna get with the champ.

Ronda was out at an event in NYC to celebrate the new UFC-Reebok partnership when TMZ Sports did men everywhere a favor ... asking Rousey what she looks for in a potential boy toy.

That's when Ronda revealed one of her biggest DEALBREAKERS.

Rihanna went all Cara Delevingne on fashion photographer Steven Klein at Monday night's British Fashion Awards.

Klein posted one photo -- with RiRi's hand on his face and her tongue in his ear -- with the caption, "Me+Rhianna being Naughty at the British Fashion Awards." He doesn't say what the equals.

Rihanna's attention was momentarily diverted by a blunt ... the girl has priorities.

As for Klein, he's shot big ad campaigns for the likes of Calvin Klein, Dolce & Gabbana, Louis Vuitton, Balenciaga, Alexander McQueen and Nike.

It's a question for the ages ... if you're going to run into two of your exes at a party, would you rather have two separate awkward encounters ... or an enormous one?

One Direction's Harry Styles chose the second option at Monday night's British Fashion Awards in London ... where he schmoozed Kendall Jenner and Cara Delevingne.

Styles was linked to Delevingne last September and Jenner just a few months later.

The scariest part for Harry ... Kendall and Cara came to the party together.

Comparing notes ... worst nightmare.

DeMarco Murray's former college teammate Brennan Clay tells TMZ Sports he's filing for divorce from his wife Gina ... after publicly accusing her of banging Murray behind his back.

Clay -- who played with Murray at the University of Oklahoma -- says the Dallas Cowboys superstar was his mentor at OU ... "the person who I looked up to the most as a running back and as a friend."

But Clay says everything changed when he found one of his wife's old cell phones -- which allegedly contained more than 50 "inappropriate" text messages between DeMarco and Gina which "made me disgusted."

Clay says he also found graphic cell phone pics that he believes Gina and DeMarco had sent each other.

Clay put both Gina and DeMarco on blast on Twitter Sunday -- saying, "So Demarco Murray was having an affair with my wife ..I'm done."'

Now, Clay says he's escalated the situation -- and filed for a divorce from Gina. The two have only been married for 4 months. Clay says he's currently meeting with lawyers to discuss the next step.

Khloe Kardashian doesn't care if French Montana has a side piece ... and she thinks her family should stay out of her business.

As TMZ first reported, the Kardashians had a heart-to-heart with Khloe last week ... warning her that French had used Kim as a cover during their recent trip, making it appear he was spending time with her when he was actually dogging around Dubai.

We're told Khloe scoffed at her family's advice ... she fired back, saying she's having fun and there's no expectation of exclusiveness.

The fam is concerned because of the way Khloe dealt with the Lamar situation ... defending him for way longer than most partners would. But Khloe says this is not "a Lamar situation." She's having fun ... end of story.

Porsha Williams derailed her own gravy train ... and now she has to ditch her $300,000 Rolls-Royce if she wants to keep living in the lap of luxury.

Sources close to Porsha tell TMZ ... the "Real Housewives of Atlanta" star has been getting ridiculously expensive gifts -- like the Rolls -- from a mystery sugar daddy. But we're told the dude (who's married) got fed up with her posting pics of the swag, and cut her off.

Our sources say Porsha's selling the RR because she needs a quick cash injection. It's not that she's broke -- she's still pulling in 6-figures from "RHOA" -- but since the BF cash flow has dried up ... she's suddenly gotta pay for more stuff ... like meals.

Mama June is trying to repair her relationship with Sugar Bear, and he's game to give it a second try ... so she says.

June tells TMZ ... Sugar Bear is back living full-time in the homestead and they are "working on the relationship." She admits it was damaged and Sugar Bear is hurt over her decision to reignite her relationship with convicted child molester Mark McDaniel.

June says they don't consider themselves "back together" and it will "take a lot of work" to regain his trust.

She tells us she did see McDaniel after he was released from prison in March ... something she lied about after we broke the story. But now she says, "I'm human, I made mistakes and done wrong, but no one is perfect."

June says she no longer has any contact with McDaniel.

Victoria's Secret model Nina Agdal firmly planted herself on all 4s ... then opened wide for her extremely lucky boyfriend.

The supermodel's BF Reid Heidenry gingerly hydrated her Saturday in Miami with a brewski.

And he got a reward in the end.

And how was your weekend?

Robin Thicke is clearly thankful for one thing this holiday season ... his super hot new girlfriend.

Thicke was rolling through Malibu Friday with the top down ... showing off 19-year-old April Love Geary -- and the guy looked pretty damn care free.

Robin's had a tough year -- see here, here and here -- so he's gotta be stoked to be moving on.

Plus, April looks really hot naked. That always helps.

Khloe Kardashian needs to run for the hills -- away from French Montana -- and that's exactly what her family told her during a heart-to-heart talk Wednesday.

Sources familiar with the situation tell us ... the Kardashians believe French has been unfaithful to Khloe, and their evidence centers around his recent trip to Dubai.

We're told the family believes French was hooking up with a very pretty woman during the trip, and tried to use Kim as a cover. We know they told Khloe French sought out Kim during the trip so Khloe would see pics of the 2 of them and think he was just hanging with her sis ... nothing nefarious.

We're told the Kardashians say French's plan unraveled when Kim came home and told Khloe she was literally with French 10 seconds here and there. The family is convinced he used Kim to deceive Khloe.

Macaulay Culkin was all tongue-in-cheek Tuesday night ... in the cheek of a middle aged R&B singer.

Culkin and his band, The Pizza Underground, were in Billings, MT with R&B singer Har Mar Superstar ... and he was definitely feeling the band's rendition of "Never My Love."

Macaulay was game for bumping, grinding, dipping and some pretty intense face sucking.
