Hot Mamas

10:00 AM PT -- Clooney's rep tells TMZ, Amal is NOT pregnant.

George Clooney broke his vow by taking one ... and MAYBE the reason is becoming apparent.

Amal Clooney and her husband were leaving Soho House in West Hollywood when a photog took the pics this weekend.

George -- who said he would never marry again -- is unwaveringly silent about stuff like this -- but the photos are definitely interesting.

Blake Lively doesn't need a sexy black dress for slimming effect -- 'cause even with a big ole bun in her oven ... she's a total smoke show.

The ex "Gossip Girl" flaunted her belly at a L'Oreal event in NYC last night ... creating a dilemma for all those fans who drooled over her bod long before Ryan Reynolds knocked her up about 5-6 months ago.

Kourtney Kardashian had the stomach to pose naked for Dujuor magazine.

Kourtney -- who is ready to pop with her third kid -- tried to one up Kim. When you break it down limb by limb ... she really looks amazing ... shades of Demi Moore.

Your move, Khloe.

Jennifer Lopez showed off her gymnast-level flexibility as she performed on stage at Sunday night's American Music Awards ... sending a message to other pop stars -- bow down to this booty.

The 45 year-old singer performed Sunday with Iggy Azalea ... and even though Beyonce and Nicki Minaj have reached for the ass queen throne -- this ankle-grabbing move solidifies J.Lo's position.

Brace yourselves ... Beyonce just released a new music video -- and she makes it clear ... she will NOT be outdone by Iggy, J.Lo or Kim or Nicki.

The video is for her new song 7/11 -- from the platinum edition of her self-titled album set to drop next week.

As for why she released it now ... well, the AMAs are on Sunday and she's about to get some stiff ass competition.

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.

Even MORE shots fired in Michelle Beadle's war on Kim Kardashian ... and it's all on video.

Beadle already blasted the reality star on Twitter last week over the nude shots for Paper Magazine -- and this weekend at LAX, Beadle made it clear she isn't backing off.

"What else is she gonna do? She's got no talent," Beadle said.

"She doesn't have anything else to show off ... so I get why she's doing it."

"And photoshop's wonderful."

So far, no word from Kim on the situation.

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 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".

So ... ESPN host Michelle Beadle took a shot at Kim Kardashian and her big fat ass.

After Kim K posted her brand new naked pic, Beadle went to Twitter to mock the reality star.

"Just purchased $633 in baby oil and performed an at-home lobotomy...let's do this. #BreakTheInternet #MoonRiver."

She later added ... "Are we done talking about giant, greasy poo-makers yet? #CometLanding."

Beadle isn't the only celebrity to go after Kim -- Chelsea Handler implied Kim's ass is fake and Naya Rivera also threw shade ... saying, "You're someone's mother."

Kim Kardashian's ass is the biggest news in the world today -- and that's only somewhat overstated -- but her wallet remains the same size ... because we know she got bupkis for the pic.

Our sources at Paper Magazine say ... Kim's sole motivation was working with famed photog Jean-Paul Goude. The mag does not have the money to pay Kim her market value, so compensation was never really an option.

We now know the shoot went down during Paris Fashion Week in September. The plan was to shoot just one cover, but she and JPG hit it off so well they "got creative" and shot a lot more.

We're told there'll be more pics coming out later this week.

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.
