Hot Mamas

If nothing else ... Chris Brown was swimming in the right end of the gene pool when he knocked up his baby mama -- as evidenced by these pics.

As we told you ... the mother's name is Nia -- a 31-year-old from Texas who used to do some modeling, and she also appeared in music videos. We're guessing that's how she first hooked up with Chris years ago.

Nicole Murphy likes 'em big ... real big ... and younger from the looks of things down on Miami Beach.

The reality star was hanging with enormously buff Brit model David McIntosh over the weekend. Considering she split with ex-NFL stud Michael Strahan last August ... it definitely looks like the lady has a type.

But sources connected to Nicole tell us despite their perfect physiques (she's freakin' 47) being so close ... they only hooked up for a photo shoot. No banging. Not yet.

The two of them together though -- quite a body of work.

Cindy Crawford's stock in trade is her body and now her people are out for blood, claiming the person who posted this pic (above) severely altered it to make her look bad.

The lawyer for Cindy's photographer

-- obtained by TMZ -- threatening everyone who posted the pic with a lawsuit if they didn't take it down and apologize. The lawyer says the original pic was stolen and then doctored to make her midsection look haggard.

The lawyer included a statement from the famous photog, who says he took the pic for Marie Claire Mexico and someone stole it from him and Photoshopped it.

The letter apparently worked ... some media outlets are already complying.

Shortly after the altered pic hit the Internet, Cindy's hubby, Rande Gerber, posted the pic below, showing the real deal.

Major props to Kim Kardashian's Instagram minions -- because without them ... you wouldn't be staring at her bare ass cheeks right now.

Kim uploaded a shot of herself sporting a thong -- ass-side up, of course -- to her Instagram account to celebrate reaching 27 million followers.

For what it's worth ... it appears to be a throwback pic, since Kim was in London Wednesday night (for the Brit Awards) -- we're doubting she packed swimwear.

There. Don't say she never did anything for you.

Beyonce was bouncing all over L.A. ... because her tatas went commando while house hunting with Jay Z.

Shopping for a new home can be liberating -- and it certainly was for Bey's girls ... which got some freedom and sunshine during a lunch break at Gracias Madre in West Hollywood.

As we've reported ... Jay & Beyonce have spent several months searching for the perfect L.A. house to purchase and make their West Coast HQ.

Just a feeling, but something's gonna open up for them soon.

The apprentice has become the master ... so says former NBA star Jalen Rose who tells TMZ Sports in the battle of the bods, he's riding with Jen Selter's MOM.

The 21-year-old ass model posted a mother-daughter bikini pic Wednesday ... showing off her 47-year-old mother's insanely sculpted physique ... and the Internet went wild.

We asked the ESPN analyst to pick just one ... and Mr. Rose put it this way -- Jen's mom is on Varsity ... Jen's on J.V.

Apparently, the apple bottom doesn't fall far from the tree.

Here's 21-year-old butt selfie goddess Jen Selter (right) posing with her 47-year-old mom Jill Selter (left) ... showing off their incredible mother-daughter physiques in tiny white bikinis.

Jen -- whose ass has a 5 million person following on Instagram -- says her mom hits the gym 4 to 5 times a week ... and clearly, it's paying off.

FYI -- Jen is also her mother's personal trainer ... so ... good work!

"House of Style" host and "Las Vegas" star Molly Sims has just learned there's a string attached to hot chicks getting out of traffic tickets ... it doesn't apply when you're pregnant.

Molly got pulled over Thursday AM because she didn't have plates on her Beemer. She did something people generally don't do ... get out of the car and walk over to the cop. It looks like a model move, but you see Molly is expecting, wearing a house dress and, well, she got wrote up.

But Molly is no sore loser. Watch the video and see what she does to the cop.

Giuliana Rancic hit the red carpet at the Grammys and everyone noticed.

The TV host hobnobbed with celebs before the show. Saturday, she tweeted about a pre-Grammy feast, saying, "Tons of sushi and finishing off an entire bread pudding. #dinnerofchampions #whateverittakes."

Madonna's ass probably couldn't make it in a Nicki Minaj video these days ... but that's not stopping her from exposing it like it's 1992 again.

The 56-year-old arrived at Staples Center for the Grammys in a sexy matador outfit, and decided to get medieval on photogs -- by hiking up her dress and showing off her aging cheeks.

Later on stage, her butt took on a bunch of half naked masked men with horns.

She keeps getting older, but her ass is ... also getting older. She just hides it well.

Brandon Marshall is a dad ... TIMES TWO ... 'cause his wife Michi just gave birth to twins last month -- and the NFL star says she's already bounced back to her pre-baby weight!

The Chicago Bears wide receiver says the kids just celebrated their 6 week birthday -- and just like Wladimir Klitschko, he's super impressed with his bad ass wife.

"My beautiful wife is not from this planet," Marshall says ... "6 weeks post baby (×2) and she's already at her pre baby (×2) weight. Her discipline with her diet and mutant genes has her #snapback game #CRAZY."

Congrats!

Tyson ... Ali ... Rocky -- they've all got NOTHING on Hayden Panettiere ... or any other woman who's ever had to give birth ... so says Hayden's boxing superstar baby daddy Wladimir Klitschko.

Wlad says Hayden's pain tolerance must be through the roof in order for her to have pushed out their giant baby 2 months ago ... saying he now believes women are WAY tougher than any boxer.

"Every woman is a hero."

Hayden might be more of a hero than most ... considering their daughter Kaya was 7 lbs., 14 oz. and damn near 2 feet tall. Hayden's only 5 feet tall.

Kim Kardashian was way ahead of the curve ... training a camera on herself when she was just 4.

We're told Kim's "Selfish" book contains pics she took of herself in the year George Orwell made famous. She picked up a camera and instinctively decided there was nothing better than photographing herself ... so she did.

Here's what Kim said in pitching the book, "I took pictures of myself with digital cameras when I was in junior high and high school, and I just got hooked." And this will shock you ... she says, "I was always obsessed with selfies."

And we're told ... the book was Kanye's idea. He titled it and his creative team -- Donda -- came up with the look.

It's due out in May.

On the left we have Amber Rose, jet-skiing earlier this week in Miami ... while on the right we have Kim Kardashian, putting her ample backside to good use while vacationing in Thailand last year.

The question is ...

One thing you can say about Amber Rose ... she's a crack jetskier.

Amber made waves Monday as she traversed South Beach in all her glory.

Amber Rose ... gluteus to the maximus.

Lisa Rinna abides by the motto, "If ain't broke, don't fix it!" -- because she attended two parties ... 10 years apart ... in the exact same dress!!!

Care to venture a guess which photo was taken over the weekend and which was taken in 2005?
