Hot Mamas

Here's the reportedly 6'1" American made super model Karlie Kloss (21) towering over the reportedly 5'11" Brazilian bombshell -- and mother of two -- Gisele Bundchen (33) at an awards ceremony in New York City last night.

Say goodbye to Pamela Anderson's iconic long blonde hair -- the "Baywatch" legend has pulled a full-on Michelle Williams, chopping her beautiful flowing locks in order to more closely resemble a 12-year-old boy.

But let's give credit where it's due. Macaulay Culkin has been rocking this noise since the 90s.

Kim Kardashian says the negative media coverage surrounding her pregnancy "HURT MY SOUL" ... and now she says she's going to live a "more private life" because of it.

Yeah. Sure.

Look, Kim definitely has a point -- some people were downright mean when she was knocked up (we can recall a tabloid headline that read, "Kim Can't Stop Eating!")

But when Kim went on "The Tonight Show" last night and told Jay Leno that she was so affected by the negative criticism of her pregnancy that she'll be taking the fame-whoring down a notch, we weren't exactly convinced.

Exhibit A -- the butt-selfie
Exhibit B -- the baseball stadium wedding proposal
Exhibit C -- THE 15 CARAT DIAMOND RING!

Then again, we could be wrong. You buyin' it?

Kim Kardashian started an ass-selfie trend ... 'cause after she shared her bikini-wedgie with the world ... ANOTHER wanna-butt celeb is following suit.

This time, the chick showing off her donk is Mercedes "MJ" Javid from "Shahs of Sunset."

It's definitely a change of pace from Kim ... and pro surfer Anastasia Ashley, who beat MJ to the punch with a butt-selfie last week.

Butt-selfies -- sometimes they're not all they're cracked up to be.

"Real Housewives of Beverly Hills" star Kyle Richards won't let 4 children stop her from slutting it up on Halloween -- in fact, the 44-year-old tells TMZ, she's already purchased her risque costume for 2013.

Richards was at an event in L.A. Wednesday night when we asked how sexy a mom should dress on All Hallows' Eve -- and Richards said she had ALREADY purchased her costume from Trashy Lingerie in L.A., a store famous for its slutty duds.

But she says she did restrain herself a LITTLE for the sake of her kids, adding, "I ended up with [a more conservative costume] because I am a mom."

Of course, "conservative" at Trashy Lingerie just means your ass isn't showing ... completely.

Meet the woman Pauly D knocked up on the first try.

Amanda Markert -- a Hooters' alum who worked as a VIP hostess when she and Pauly got wasted in Vegas and had unprotected sex -- is what you expected to see. Check out the photos.

It's not all sunshine for Amanda. She's now the mother of 2 who is waging legal war with Pauly over custody of 5-month-old Amabella.

She's been naked for Playboy ... and donned itsy-bitsy bikinis for Sports Illustrated ... so it's no wonder Stephanie Seymour wasn't shy when it came to trying on lingerie in Italy yesterday.

The 45-year-old model grabbed some racy outfits while shopping at Agent Provocateur in Milan with her 66-year-old husband Peter Brant ... and tried them on right in front of the store window. It was awesome.

FYI -- Peter Brant is a paper mogul who happens to be a frickin' BILLIONAIRE!!!

So, good for him ... and good for her.

There's "No Doubt" Gwen Stefani's looks are rock steady.

Here's the 28-year-old punk rock princess putting her best bindi forward at the Grammys back in 1997 (left) -- and 16 years later the 44-year-old mother of two (soon to be three) at a gala last week (right).

39-year-old Kate Moss isn't holding back before her big Playboy spread in January, removing her bikini top on the beach in Jamaica yesterday -- and she doesn't look half bad.

FYI, Moss will be gracing the cover of Playboy's 60th anniversary issue ... the same month she turns 40.

Jamaican us crazy.

Kate Middleton allegedly had a baby 3 months ago -- but there is zero proof of that in these pics of the Duchess of Cambridge flashing her royal midriff all over a volleyball court.

Prince William's wife showed up for a public appearance in London yesterday, sporting wedge heels, and a banging bod that made everyone forget she was ever pregnant.

Kate gave birth on July 22 to Prince George ... and obviously hit the gym on July 23.

Women ... begin hating. Guys ... continue wishing you were Prince William.

If you think Kanye West is proprietary about Kim Kardashian's ass, think again, because he clearly believes it's awesome and is glad she's sharing it with the world.

We're told his response when he saw Kim's Instagram pic was that he loves having a hot chick.

Kanye retweeted the link to the photo and wrote, "HEADING HOME NOW." In case his message isn't clear ... it was put to us this way ... he's proud of it because it's his girl.

Kanye West -- into sharing.

Kim Kardashian's gargantuan ass is back in working order ... and last night, she let the world know ... with a backside selfie on Instagram

It's the first butt-selfie Kim's taken since giving birth to Kanye West's baby North back in June.

Kim's been on a serious sexuality kick lately -- on the most recent episode of her reality show, she talked about wanting to pose NAKED asap ... saying, "As soon as I get in shape, the first thing I want to do is Playboy or some nude shoot. I just wanna walk down the street fully naked."

Looks ready to us.

Katie Holmes has broken out of her frumpy phase in a SERIOUS way ... strutting around the streets of NYC today looking downright sexy.

Of course, Katie has never really been unattractive, but there was a rough period ... right before she broke things off with Tom Cruise.

But after the two split in 2012, Katie began a Tiger Woods-style comeback ... in the hotness department ... going from a 9 back to a 10.

Nice work.

Here's Victoria's Secret supermodel Alessandra Ambrosio taking a bite out of an actual piece of edible pizza in L.A. yesterday ... and carefully contemplating whether or not to spit it out.

It's not the first time Alessandra cheated on her supermodel diet -- earlier this year, she was spotted chewing on a breadstick in an L.A. supermarket.

Also, in 2012, she was photographed taking a bite of chocolate cake ... and was spotted with an ice cream cone in 2009.

Glutton.

It's a Colombian face-off!

Here's 41-year-old Colombian born and "Modern Family" star Sofia Vergara posing in a little black dress (left) -- and 25-year-old second generation Colombian and "Spy Kids" actress Alexa Vega in an equally little and equally black dress (right).
