Hot Mamas

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.

OK, we're spent. Your turn.

Wanna see Jamie Foxx sweat? Tina Knowles put him in a serious bind by putting her ass dangerously close to his crotch while dancing last night.

Mama Knowles jumped on stage during Jamie's performance at the Angel Ball in NYC Monday night -- and decided to back, back, back it on up ... right into Awkwardville.

And that's when Jamie starts sweating. His options:
- Totally go for it and give Beyonce's mom the ride dance of her life
- Politely back away because that's Jay Z's mother-in-law.

And, of course, he doesn't wanna hurt Tina's feelings either, so ... watch to see how Jamie handled it.

Kris Jenner is way more bush league than we thought ... if you want to make yourself look younger by photoshopping, don't do it AFTER someone else posts the pic of you looking older than you want.

Kris is hawking her new cookbook and Gordon Ramsey gave it his stamp of approval. But check out Gordon's Instagram and then compare it to Kris's. Clearly she doesn't believe cookbooks get better with age.

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.

The celebrity nude photo hacking scandal has gone MILF ... as topless photos of Carrie Michalka -- mother of Aly and AJ Michalka -- have leaked online.

The photos of the mama Michalka all appear to be selfies and her face is clearly visible. There is also a revealing video of Carrie (who used to be in a Christian band) shooting herself in the mirror.

Aly and AJ were also victims of the hackers ... with shots purporting to show them topless (not together, no faces) leaking during the first round of photos.

We reached out to Michalka for comment ... so far, no word back.

Even Queen of Soul Aretha Franklin needs support from time to time.

'Retha's making headlines for her amazing cover of Adele's "Rolling in the Deep" -- and she was showing off her ball gown swag Monday in NYC after taping an episode of "The Late Show with David Letterman."

She's a natural woman.

The apple doesn't fall far from the tree ... when we asked Keyshia Cole's mother what she thinks of Birdman ... she was ready to go to blows.

As TMZ first reported, Cole was arrested last week for allegedly attacking a woman partying in Birdman's condo. Cole and Birdman are reportedly dating ... so you get why she was upset -- though the alleged victim claims nothing happened with her and Birdman.

At Cole's album release party Sunday night, Keyshia's mom clicked into Protective Mother mode.

Kanye West is protecting his gluteus to the maximus.

Kim and Kanye are in Paris for Fashion Week and Mrs. West posted a picture on Instagram of Yeezus showing his affection for her backside.

As we previously reported ... Kim upped her security detail this week after she was almost tackled to the ground by a crazy person during an event in Paris.

Good thing Kanye's got her ass covered.

Once again preparing to bless the world with another Spawn of Disick, Kourtney Kardashian showed off her pregnant body while lounging poolside in Los Angeles.

This will be the third child for KK and SD -- they already have son Mason, 4, and daughter Penelope, 2.

Kourtney told Scott she was preggers on the season premiere of "Keeping Up With the Kardashians" and his reaction was amazing.

With her backside back in the headlines, 45-year-old Jennifer Lopez put her most prized asset front and center while performing Sunday night at the Singapore Grand Prix.

Jennifer Lopez looks so good in lube in her new "Booty" music video with Iggy Azalea -- she now stands to make a bundle off a company that makes the stuff.

Reps for Doc Johnson Lube fired off the sticky to proposal to J.Lo after seeing the video last week -- and we're told they were especially inspired by the shots of her covered in a liquid they believe to be personal lubricant.

Bottom line -- Doc Johnson wants to be in the J.Lo butt business ... and the company is offering her a year's worth of its lubrication gel for free to prove it. The good doc also wants to discuss a long term sponsorship deal, if Jennifer's interested.

Something tells us this is NOT right up her alley -- but can't knock 'em for trying.

Iggy Azalea is one big-ass contradiction ... she's running from a sex tape her former BF made, but she just dropped one of the hottest, most sexual videos EVER with Jennifer Lopez.

Just watch and behold the video -- "Booty." Whatever your sexual orientation, you will be turned on. Seriously.

Iggy and JLo grind crotches and slap each other's asses ... with commitment.

It's also very wet ... after they oil up. BTW ... there's also music, but seriously, who cares?

Los Angeles Lakers star Nick Young is a huge friend of his GF's ass ... and so is Jennifer Lopez ... 'cause J.Lo and Iggy Azalea are twerking ALL OVER EACH OTHER in a new video that just hit the 'net.

Lopez just released her new video for "Booty ft. Iggy Azalea" ... and really it's just an excuse for the two badonkalicious women to show off their backsides.

There's booty shakin ... booty slappin' ... booty twerkin ... booty on booty action.

It's insane.
