Hot Mamas

It's a battle of the booty!

Here's Jennifer Lopez showing off her 45-year-old bulbous backside (left) posing with 24-year-old Iggy Azalea's down-under donk (right) in a photo promoting their upcoming remix together.

A freshly single Paula Patton re-emerged back out on the scene Monday night, hitting up Craig's in West Hollywood for a post-Emmys bash ... the first time she's been seen out since her break-up from Robin Thicke.

Sarah Jessica Parker displayed a panoply of emotions Friday.

SJP was hawking her new shoe collection at Nordstrom's in D.C. ... showing off her range of facial expressions.

Sylvester Stallone is destined to do an "Expendables 15" if genetics has anything to do with it ... because we got photos of his 92-year-old mom doing CrossFit!

Jackie Stallone is a certified bad ass ... with no machine in the gym out of bounds.

During her workout, Jackie hits the rowing machine, rings, medicine ball ... and even gets in some squats before knocking out a few bench presses.

Kim Kardashian stepped out of her New York City apartment Monday afternoon with a slew of fans waiting to catch a glimpse of her ... including Officer Staresalot over here.

But really ... he's doing NOTHING wrong. In fact, he's supposed to be watching her ... and he is.

Heidi Klum nearly posted one of the best photos in the history of Instagram ... if only designer Zac Posen had kept his damn hand to himself.

Klum, wearing nothing but a pair of tiny panties, posted the photo with the caption: "@zac_posen ....I need something to wear for tonight's @projectrunway @lifetimetv."

Gisele Bundchen frolicked around on the beach Tuesday in Costa Rica ... crawling around in the ocean with her adorable dog Lua.

Hurry up and look at this photo of Elle MacPherson in a bikini, because at some point she's going to return to her home planet and we'll never see her again.

The 50-year-old supermodel (kids, this is what a supermodel looks like) posted the ridiculous photo to her Twitter page the other day, with a caption reading, "Super greens... After super swim."

As if you needed more proof Elle looks INSANE for her age ... Courtney Love just turned 50 as well.

Rock on, Elle.

Wearing a tiny pink bikini, 43-year-old Denise Richards showed off her fantastic body ... looking as if "Wild Things" came out last week and not 16 years ago.

When you factor in she's had two kids ... and had to deal with her Charlie Sheen drama ... it's even more amazing.

Jenny McCarthy is not spending time in a dark living room ... crying over her "View" firing. Quite the opposite ... she's giving strippers a run for their money.

Jenny hit up a cabaret show in Miami over the weekend after performing at a comedy show and her boobs were in full blossom, though not as much as the day before, when she showed up at a pool party in Vegas.

And she showed up Monday on Howard Stern's show.

Jessica Alba's ass is vacationing in Cabo ... which definitely makes Cabo the hottest place in Mexico.

This is what 33 with 2 kids looks like, people.

Jennifer Lopez's booty busted into some new territory -- twerking like a twenty-something during her iHeart Radio concert ... even though she's 44!

It's either one giant leap for uhh ... more experienced asses -- or totally thirsty.

She's 23 years OLDER than Miley Cyrus ... but Jennifer Lopez was out to prove she's the real TWERKING QUEEN during a booty-bouncing performance in Miami.

JLo and her big 'ol butt hit the stage at the "iHeartRadio Ultimate Pool Party" on the CW last night ... and threw her glutes around like a 44-year-old CHAMP during her new aptly-named hit, "Booty."

So, the real question ... how do Ms. Lopez's twerk skills match up with 21-year-old Miley??

What's the greater miracle ... an astronaut getting pregnant after spending a year alone in space ("Extant" ... coming soon!) ... or Halle Berry's nipple somehow popping out of a dress that seemingly appears nip-slip proof?

Jennifer Lopez contorted her body into all sorts of positions this weekend ... rehearsing before her gig at the iHeartRadio Ultimate Pool Party in Miami.

Jenny McCarthy's looks have never been let go.

Here's the then 23-year-old "Singled Out" host at the MTV Movie Awards in L.A. back in 1995 (left) and 19 years later -- the now 41-year-old "The View" outcast at an NYC party earlier this year (right).
