Beauty

Justin Bieber is wise enough to know when a gift needs givin' ... but he didn't have a box -- so he covered his junk with a guitar and jammed out a naked serenade for one lucky lady fan -- HIS GRANDMA!

TMZ has obtained photos of a completely nude Biebs strumming away on his big wooden instrument ... at his grandmother's home in Toronto during Thanksgiving back in November 2012.

And why, you ask, did Bieber go ass naked for g-ma?

Our sources tell us JB had been staying at his granny's house during the holiday ... and slept in a little too late on Thanksgiving morning.

Bieber finally woke up after hearing family and friends stirring around the house -- so he thought he'd prank 'em ... by grabbing his guitar and playing a naked set a la Jenny from "Forrest Gump" ('memba that?).

We're told birthday-suited Bieber went right up to his grandma and started belting out some impromptu lyrics ... like, "I Loooove you grandmaaaa ... how are youuuu ... helloooo grandma."

We're told G thought it was pretty funny -- and everyone in the home was cracking up -- but granny begged the pop star to get back in his room to put some damn clothes on, stat.

Thanksgiving -- they go balls out.

More than THREE DECADES after he went topless in "Fast Times at Ridgemont High," Sean Penn struck a Spicoli pose in Spain ... and proved he's more JACKED than ever.

Check out this pic of Sean back in 1982 -- when he was 21 years old -- and then make a decision.

Rehab does a body good ... as evidenced by this picture of Lindsay Lohan looking less like a blowfish and more like a completely regular human.

If supermodel turned television host Heidi Klum was saved onto a floppy disk and given a pair of played out white wayfarer sunglasses she'd turn into the '80s stuttering electronic character Max Headroom.

Al-al-al vita zein!

Beyonce Carter crushed it when she decided to chop off all of her hair -- 'cause when it comes to style, B can do NO WRONG ... so says her Destiny's Child bandmate Kelly Rowland.

"Beyonce can have a STRAND of hair on her head and still be fine," Kelly told TMZ as she was leaving Madeo in L.A. last night.

But it's not like Beyonce revolutionized women's hair fashion when she decided to hack off her locks -- 'cause as Kelly tells us, "We have been rocking short haircuts since the beginning of time."

In fact, Kelly had a pretty short 'do way before Beyonce did -- and looked great -- but even Kelly admits it wasn't that original of an idea at the time.

NBA player Jason Collins hit the West Hollywood club scene last night ... and ran into former "American Idol" star Adam Lambert at a new place called Hooray Henry's.

One is beautiful ... one is brilliant ... and they're all bangin' Charlie -- at least, that's the presumption because Mr. Sheen's new "angels" are all well versed in the art of screwery, TMZ has learned.

After some hardcore research -- and we mean HARDCORE -- we've finally identified all three of Charlie's new lady friends ... and, shocker, they're all veteran porn stars.

Ladies and gentlemen ... but mostly gentlemen ... meet (from left to right) Jayme Langford, Jana Jordan and Celeste Star.

A few fun facts about Charlie's Angels:

- Jana Jordan has starred in more than 100 adult films including Power Munch 3 & 5 ... and she's been nominated for a ton of AVN awards.

- Celeste Star doesn't just act in porn ... she's also a porn director ... although she currently only has one film under her belt.

- Jayme Langford studied bio-ethics at the University of Judaism in Los Angeles. UJ officials pulled her financial aid though after discovering she had starring roles in a bunch of porn flicks.

Bonus Fun Fact: The blonde and the redhead have shot at least 2 sex scenes TOGETHER. There might be more ... but our computers are gonna go blind if we continue to research.

Charlie Sheen's Goddess-less days are over ... the warlock has found three NEW porn star girlfriends -- but this time he's calling them "Angels". Get it, like "Charlie's Angels".

TMZ obtained pics of Charlie and his harem vacationing in Hawaii recently. Keeping to the theme, he chose a blonde, a brunette and a ginger -- who go by JL, JJ, and CS. Who knows which is which.

From the pics it's clear Charlie had a great time with his ladies -- probably because they were topless.

We're told the orgy party didn't stop in Hawaii either ... the XXX stars are now shacking up with Sheen in L.A. ... kind of like it's 2011 all over again.

Tyra Banks is a SUPER model.

Here's the natural looking 21-year-old smizing for a photo outside of a NYC comedy club back in 1994 (left) -- and 19 years later the 39-year-old model turned TV host serving face on a late night show earlier this week (right).

Tamera Mowry will do whatever it takes to stay right and tight ... down there ... even if that means blasting hot steam and weird Korean herbs into her hoo ha. But would she do it again?

On recent episode of "Tia and Tamera" the sisters were seen getting a V-Steam: an ancient Korean tradition where women sit on a toilet-like apparatus and have a mixture of hot steam, mugwort tea and wormwood blasted into their vagina ... to make it fresh. Really, it's a thing.

So when our photog spotted Tamera in LA this week he HAD to ask ... what was it like?

Tamera (who had a baby last November) gives us the low down on what the vag-bath did to her lady bits -- it's pretty hilarious -- and reveals whether she'd go back for round 2.

Forget babies, food and cat photos -- these stars were so proud of their bronzed backsides they took to the interweb to shared their beachin' butts!

Can you guess which sexy stars are the proud owners of these perfect posteriors?

Former FHM model Anna Benson -- who has just been charged with armed robbery and all sorts of other crimes -- is no stranger to the law. She was once charged with murder.

A judge has denied Benson bail in her current legal predicament -- for allegedly barging into the home of ex hubby former Mets pitcher Kris Benson with a handgun and a metal baton and threatened to harm him if he didn't hand over some loot.

As for why she was denied bail -- turns out back in '96 Anna was charged with murdering a man in Tennessee and she went on the lam for 5 months. Although the charges were ultimately dropped, the judge in the current case felt because of her conduct in '96 Anna is a flight risk.

Justin Bieber came out smelling -- and looking -- like a rose in NYC after hitting up a tattoo parlor for fresh ink last night.

Justin's left arm is one step closer to a full sleeve today ... after getting a blooming rose on his elbow to fill in an awkward bare spot.

The Biebs was even nice enough to pose for pics with some fans waiting outside the ink shop.

Still ... we gotta give him 3 douche points for the sunglasses at night.
