This is it ... the last bikini objectification of the year ... and so, we proudly present -- KATIE HOLMES VS. JENNIFER ANISTON!!!!

Two hot bodies -- but there can only be one winner.

So, we gotta ask ...

Audrina & Cheryl Burke Screw 'Dancing' ... IT'S BIKINI TIME!!!

"Dancing" does a body good ... and Audrina Patridge and Cheryl Burke are the proof.

Still, we gotta ask ...

Cindy Crawford and Fam They Just Look Better than Us

Wanna feel bad about yourselves this holiday season ... then check out the couple that never ages and the daughter who looks exactly like her beautiful mom.

Cindy Crawford, hubby Rande Gerber and their daughter Kaia were tooling around the Farmer's Market in Malibu Sunday.

-- Cindy looks as good as she did 20 years ago

-- Rande probably still gets carded at the bars he owns

-- Kaia is going to make millions modeling

Eating right, exercising, getting lots of sleep ... overrated. It's all about good genes.

Martin Sheen GOOD GENES OR GOOD DOCS?

Martin Sheen's looks are not "Badlands."

Here's the 35-year-old version of the "Apocalypse Now" actor giving a grimace back in 1975 (left) -- and 38 years later, the 73-year-old "The West Wing" alum shootin' the same smile at a gala in Dubai (right).

Marlon Wayans Bruce Jenner Should 'Get the Breasts Already'

0-15x58pwx

Marlon Wayans believes Bruce Jenner's laryngeal shave is the first step toward becoming a woman -- but he's moving too slow -- telling Bruce, "Just get the breasts" already!!"

We broke the story, Bruce already consulted a plastic surgeon about reducing the size of his adam's apple -- though Bruce insists it's NOT the first step of gender reassignment, it's just because he doesn't like the way his throat looks.

Still, Marlon ain't buyin' Bruce's explanation -- and on his way out a "What the Funny" event he told us, "I think slowly but surely he's been turning himself into a woman all these years."

"Why don't Bruce Jenner just go and get the titties now ... just get the breasts."

In the end, Marlon says if Bruce continues down the surgery path ... "He's gonna look like me in 'White Chicks.'"

Tyson & Courtney Don't Be Afraid Of the Dark

If Tyson Beckford's beautiful ripped body doesn't do it for you -- check out Courtney Stodden's massive ... head of freshly darkened hair! Oh, and her boobs too.

Yes, like a young Anakin Skywalker -- we're going to the dark side.

Victoria's Secret model Cara Delevingne is a HERO ... 'cause she just posted video of some of the VS supermodels TWERKING behind the scenes at the fashion show ... and it's awesome.

The Twerkers -- Doutzen Kroes and Joan Smalls.

Both women were hangin' out backstage in their robes, when they decided to start throwing their asses around ... while Cara sang the words to Major Lazer's hit, "Bubble Butt."

The footage was shot back in November, but Cara held it until the show aired on CBS last night.

It's ok ...we forgive you.

Ryan Seacrest's new lady Shayna Taylor nearly FROZE TO DEATH during her first big modeling shoot yesterday -- stripping down to a tiny bikini on an L.A. beach in the middle of the winter -- but even though it was cold outside, the photo shoot was hot as hell.

As we reported, the 23-year-old smokeshow just signed with a huge modeling agency thanks to the publicity she's gotten from allegedly dating the "American Idol" host.

Check the video ... she's a natch ... but she still needs a little coaching from the photographer.

FYI, it was roughly 45 degrees in L.A. yesterday by the water ... which is like -76 degrees for Angelenos.

Plus, she's really hot.

A rep for Wilhemina tells us they believe Shayna has "huge potential in the fitness and lifestyle world."

Especially when one of the friends looks this damn hot in a bikini.

Lindsay Lohan CHECK OUT MY SMOKIN' HOT ASS ... It's Bathing Suit Season

It's the first time Lindsay's really shown off her body since leaving court-ordered rehab back in July, stemming from a reckless driving conviction.

Joey Fatone I Got New Hair ... But It 'Aint No Rug

Joey Fatone just said bye, bye, bye to balding -- the ex *NSYNC singer has a brand new 'do, and it's totally real ... courtesy of Bosley hair restoration.

Joey says he started going bald during *NSYNC's heyday, but wore hats to hide it ... adding, "It was pretty intimidating. That's life, but the beautiful thing is that now you can do something about it."

If Fatone sounds like a pitchman ... it's because he is now. Joey just shot a new commercial for Bosley.

If only something could have been done about Justin Timberlake's cornrows.
