Celebrity Butts

There've been lots of Photoshopped iterations of Kim Kardashian's Paper Magazine shoot -- but only one man has dared to drop trou and put his real butt on blast.

Showman Jeff Beacher adorned himself in a wig, pearls and black lacy gloves in his homage to KK. The owner of the MGM Grand party palace Beacher's Madhouse showed no shame and no mercy.

**WARNING -- SO. MUCH. BUTT**

Floyd Mayweather sure loves crack ... and he proved it by posting footage of a 10-on-1 twerk session in what appears to be his hotel room.

There is so much jigglin.

Floyd also posted this caption, "If GOD made anything better than a woman, I don't want it" #mrmylifeisthesh*t #tmt #tmg."

The very beginning of the footage shows Floyd laying face down on a massage table in his boxers ... enjoying the view.

Italian model Claudia Romani looked amazing in her tiny bikini frolicking at the beach. Only problem is ... it looks like she’s swimming through sewage.

We like our smoking hot models extra dirty, but this isn’t what we had in mind.

The so-called "untouched" pics of Kim Kardashian's ass circulating online are not real ... this according to the magazine that published the real deal.

The pics that are circulating show what everyone expects to see ... dimplings, rolls, a wider waist and stretch marks. The pic on the left is almost a cartoon version of reality. The pic on the right is a little better, just showing uneven cheeks.

A rep for Paper Magazine tells TMZ none of the photos are authentic. The Chief Creative Officer for the mag said on TMZ Live ... none of the Photoshopping they did was drastic.

The fakes going around are all over the place ... some make her ass look bigger, others make it look smaller.

Size matters.

Kim Kardashian took her Internet-breaking ass out in Beverly Hills last night ... prompting new talk about whether the instantly famous cover shot is Photoshopped -- or how MUCH it was Photoshopped.

Kim stopped and posed for pics outside Kendall James Salon -- but the best part of this video is when she's walking away ... because it's video, and we KNOW it hasn't been altered.

Admittedly, it's not the perfect comparison -- she's wearing clothes, after all -- but it's worth a look ... a long hard look.

Kim K ain't got nuthin' on Sir Chuck.

Tyga just upped the ante in his pissing match with Drake ... by grabbing a giant handful of his ex-chick's ass and signing her to co-star in a new music video.

Sources involved in the deal tell TMZ ... Tyga asked Dollicia Bryan to be in his "Make It Work" video specifically because the song includes lyrical jabs at Drake, like -- "Ni**a never was my homey ... all these bitches know you corny ni**a."

Drake's been flirting with Tyga's baby mama Blac Chyna on social media for weeks now -- so, not shocking that Tyga bagged Dollica.

In fact, we're told Tyga flat out told Dollicia he was using her to piss off Drake ... and she jumped at the opportunity.

Exes be trippin'.

Kim Kardashian just revealed the whole enchilada.

More pics just surfaced from the Paper Magazine photo shoot with famed photog Jean-Paul Goude. The pics were taken in Sept. during Paris Fashion Week.

We've learned this pic was taken after the now-famous ass photo, when Kim decided to put everything on display.

As we reported ... this is Kim's last stand before getting pregnant again, which she plans to do shortly.

Her big thing was to show the world how she bounced back after giving birth to North West.

Sir Mix-A-Lot likes big butts and he cannot lie, but when it comes to picking the best of them all -- the brother just can't deny the round thing that gets him sprung ... belongs to Jennifer Lopez.

Yes, Mix tells us he's been admiring Kim Kardashian's latest cake displays -- but still gives more weight to J.Lo's experienced bubble. In fact, he says her ass inspired him to write "Baby Got Back" ... after seeing it in all its Fly Girl glory on "In Living Color."

For now, Kim's gonna have to settle for a consolation prize from Mix ... who says J.Lo's 45-year-old ass still isn't ready to hand over the crown.

For the record Mix ... Kim actually IS 5'3".

If Kim Kardashian made the Internet explode with her ass photo ... Chelsea Handler just made the rubble bounce.

Chelsea posed sans oil, and as far as we can see it's not Photoshopped ... which makes it extremely impressive.

Handler is making her body parts a name for themselves ... she went to war with Instagram last month after they took down her topless photo mocking Vladimir Putin.

Did we say she has a nice ass?

Chelsea's going in on IG again -- she just REposted her topless Putin shot with a caption questioning why the app is cool with shots of Kim K's bare ass (and Chelsea's too) ... but not cool with her exposed boobs. She added, "I'm just so confused."

Kim Kardashian shot the instantly iconic ass photo because it's her last stand before getting pregnant again ... TMZ has learned.

We know Kim is telling close friends and family she's about to get pregnant again, and wants to show off her body before the weight gain. She's proud she dumped the weight after North was born and wants to show her tight figure off.

As for Kanye ... we're told he's the opposite of jealous. He loves her public displays.

Our sources say there were a number of pics the photog took and they will be released soon. The photog -- Jean-Paul Goude, is famous for shooting nude celebs, including Naomi Campbell.

The Kim pic is actually a recreation of the famous champagne photograph that Goude shot in 1976. The model is Carolina Beaumont.

Goude shot a similar pic of Grace Jones. And get this ... another photog copied the Grace Jones pic, using Amber Rose as the model. Amber, of course, was Kanye's GF before he hooked up with Kim.

And we're told ... this will not be the last nude photo shoot before Kim gets pregnant again. She plans a few more, but it'll happen soon because she wants baby #2.

Naya Rivera apparently is a member of the minority that's not a fan of the Kim Kardashian asstastic Paper magazine cover photo.

While Kim was breaking the internet, Naya was throwing shade, saying, "I normally don't. But...you're someone's mother..." It takes some nerve to play that card seeing as Naya changed her face to look like Kim.

They're called MILFs, Naya. Look it up.

OK, we're spent. Your turn.

Serena Williams says there's a damn good reason she didn't run the NYC Marathon with her good friend Caroline Wozniaki ... "My ass is too big."

The tennis superstar talked her butt -- and a whole lot more -- during an "Ask Me Anything" thing on Twitter this morning ... even revealing that she "desperately" wants to have children.

Another interesting moment ... when asked if she was single, Serena wrote ... "Not by choice."

Sad, right?

Like hot butts? Like trick shots?

Then you're gonna love Sports Illustrated swimsuit model Nina Agdal hitting a crazy half court shot ... while the camera is trained squarely on her ass.

The 22-year-old Danish model fired off a shot like a pro -- and swished it -- no rim, no backboard.

Check out the vid (and thank us later) -- this isn't the first time Nina has shown her affinity for roundball -- but we gotta say, it could be the most pleasing.

Dammmmmmmmmmnn .... is pretty much all you can say about Kim Kardashian's ass-entuating outfit for a Sunday afternoon outing with Kanye West.

The couple hit up a theater in Calabasas for a movie date and on the way out Kim proudly displayed her trademark in cutoff jeans and a back-baring top -- then they hit up a Taco Bell drive-thru.

You can tell from the photo ... Kanye gives this rearview two thumbs up. Way up.

Not to be a buzzkill -- but rubbing your bare back on a movie theater seat? Risky business.
