Kellan Lutz celebrated his 30th birthday Saturday night with a flair ... at Dan Bilzerian's Hollywood Hills pad.

There were hot naked chicks and dudes wearing very little, per the invitation, which says, "The pool is heated to 95 degrees, and the Jacuzzi is on! We bought 150 white towels, and encourage everyone to bring a bathing suit (white bathing suit preferred)."

Everything was white. The invite makes it clear it's "an all white party. You will not get in if you are not wearing all white."

Looking like she just walked off set from a Tim Burton movie, Victoria Beckham walked the red carpet Thursday night with hubby David at the Alexander McQueen: Savage Beauty Fashion Gala in London.

Coco is now slanging lingerie ... and she's wearing the barely there bodywear in a new twerk video to prove it's the go-to underwear for strippers nationwide.

Ice T's wife is now the face of Cocolicious Lingerie -- launching at the end of the month -- and dropped this slo-mo video of her ass jiggling to show off her thong's bounceability.

Verifiably inaccurate.

Paris Hilton was leaving The Nice Guy in L.A. Wednesday night when our photog complimented her on her performance the other night at a bachelorette party in Las Vegas, where she faked an orgasm.

In an entirely separate encounter, we asked Kathy Hilton if she happened to see the video ... and it was AWK-ward.

Lindsay Lohan is as good at Photoshop as she is community service -- not very.

LiLo posted a photo of herself striking an awkward pose, standing in front of a door. If you look closely ... you can see she altered the pic around the ass area, presumably to make it look more robust.

Lindsay captions the pic with an admission ... she cropped out her dogs because she didn't like the way they looked.

If this is how Carl's Jr. babe Charlotte McKinney plans to rehearse for her upcoming gig on "Dancing With the Stars" -- there's at least a chance we might be interested in that show again.

Hint for the 'DWTS' wardrobe department -- save the bikinis for Charlotte, and keep them away from Redfoo ... at all costs.

Of course, it's easier (and hotter) to just watch her burger spot instead.

Jennifer Lopez slithered into a tight, formfitting red dress Tuesday and showed off her killer body as she made her way in to tape an episode of "Jimmy Kimmel Live!"

Every week, she hits your TV as the filthy Rosita Espinosa, all grimy from surviving the zombie apocalypse. But in real life, Christian gets dirty in a totally different kind of way.

Check out 11 photos of the starlet sexy enough to make you rise from the dead and earn your Woman Crush Wednesday honors.

Ryan Seacrest clearly has a type -- hot and blonde -- but his new girl is different in one big way ... she has a bambino.

The "American Idol" host was spotted out this weekend in NYC with a new blonde -- Renée Hall.

Hall (who is ... shocker!!! ... a model) met Seacrest, fresh off his breakup with model Shayna Taylor, at his 40th birthday party in Napa a few weeks ago.

We're told they met through the Marciano brothers (GUESS founders) and quickly hit it off.

Seacrest took Hall to NYC over the weekend, where they went to the Museum of Modern Art.

As for Hall's 8-year-old son, she's proud and loud, posting pics all over her Instagram page.

Ryan would be a cool stepdad, right?

Soooo ... Rob Ryan's son is a male model. And he has abs.

For those unfamiliar, Rob is the defensive coordinator for the New Orleans Saints ... and he's the twin brother of Buffalo Bills head coach Rex Ryan.

The Ryan brothers aren't exactly known for having shredded physiques ... but in the case of Joe Ryan, sometimes the apple does fall far from the tree.

Joe recently moved to L.A. for modeling ... and his dad came to town to visit.

In fact, we ran into the two on their way into the Lakers game at the Staples Center ... but for some reason, we just didn't connect the dots.

Taylor Swift put her famous (and possibly extremely valuable) gams on full display in Los Angeles for a shopping trip down Melrose Avenue.

According to a report, Swift and her team explored the possibility of insuring her legs against possible injury and learned they were valued at $40 million.

Gwen Stefani was looking hella good at her son's soccer game Saturday ... and single-handedly blew away the other soccer moms standing within a 100-yard radius.

The 45 year-old No Doubt singer was in Studio City cheering on Kingston while holding onto his younger bro Apollo. It's almost freakish how she doesn't age, especially with 3 kids.

While most of America freezes its collective buns off, huddled around heaters and fireplaces hoping for one moment of warmth, we at TMZ Sports bring you the Dallas Cowboys Cheerleaders in bikinis.

Enjoy.

One thing's for sure, Lindsay Lohan looks way better in a cream colored coat and bell-bottomed black slacks, than jailhouse orange ... which she keeps narrowly dodging.

Lohan was walking around London ... where she's been flying under the radar since an L.A. judge ordered her to perform 125 additional hours of community service.

This is the best we've seen her look in a while -- however, time spent putting together one's outfit and applying one's makeup ... does NOT count as community service.

It's unclear if LiLo's aware of that.

There is only one possible reason Scott Eastwood was working out in Santa Monica without a shirt or shoes, but WITH jeans and a giant belt buckle -- and you're looking at it.

When you've been blessed with looks and a body like that ... you show it off as much as possible.

Then again ... maybe Clint's son is just prepping for a sequel to his "Funny or Die" video where he plays with dogs. The rest of us just don't stand a chance.

Ronda Rousey spent more time throwing punches on the set of her Sports Illustrated Swimsuit Edition modeling shoot ... than she did during UFC 184 ... and now there's video of the scantily clad workout.

SI just released the video ... in which Rousey says she was WAY more comfortable doing martial arts poses during the shoot than the traditional kissy-face looks.
