Hot Mamas

Mariah Carey got a full police AND umbrella escort on her way out of an "American Idol" photo shoot in Baton Rouge yesterday -- 'cause the only thing more harmful than angry rappers are those damn UV rays.

Carey had told Babwa Wawa that she bulked up her security team after Nicki Minaj allegedly threatened to shoot her with a gun during their blowup earlier this week ... and Thursday she proved she ain't messin' around.

Sources tell us ... Mariah and Nicki both participated in the shoot -- and even posed for pics TOGETHER. We're told the shoot was peaceful, but it's clear the hatchet is not buried.

Tomorrow, the gang has another round of auditions ... and that's when tensions really start to heat up.

Christina Aguilera's massive boobs and Hillary Clinton's steely gaze proved once and for all that NO ONE -- male or female -- can ignore boobs on a platter! Well played, Madam Secretary.

Hillary Clinton is clearly impressed with Christina Aguilera.

The two got together at the 2012 George McGovern Leadership Award Ceremony in Washington D.C. on Wednesday for their work in helping feed starving children throughout the world.

Clearly, Christina has what it takes to make sure no child ever goes hungry.

Mario Lopez's 2-week wife Ali Landry is an expert on her knees, easily keeping her balance during a smoking hot paddle boarding session in Hawaii earlier today.

In case you forgot, Mario and Ali were married on April 24th, 2004. Their marriage was annulled two weeks later.

Sofia Vergara celebrated "Modern Family's" big Emmy win last night by shaking her ass like a CHAMPION in a tight sexy dress ... and TMZ has ALL of the incredible jiggly footage.

It all went down at the HBO Emmy Party at the Pacific Design Center -- when Sofia stormed into the place around 1 AM with the urge to dance her face off in her ultra-skin tight dress.

Sofia -- clearly excited her show won the statue for Best Comedy Series-- went straight to the center of the party and began gyrating to Gloria Estefan's "Conga."

With the crowd egging her on, Vergara requested the DJ play the Enrique Iglesias track, "I Like It"... and of course, he obliged.

Heidi Klum showed up to the Emmy Awards moments ago without her bodyguard boyfriend ... but fully rocking her smokin' hot body.

Klum walked the red carpet at the Nokia theater in downtown L.A. sporting a scantily cut sea-foam dress ... where the plunging neckline and high leg slits managed to meet in practically the same place.

The same day she revealed she's pregnant with her first child, Shakira was spotted out wearing a loose fitting black top with her hunky Spanish futbol player boyfriend Gerard Piqué in Barcelona on Wednesday.

While her baby news caused the 35-year-old Colombian pop star to cancel her performance in this weekend's iHeartRadio Music festival, Shakira is all set to replace Christina Aguilera as a coach on "The Voice" next spring.

Brazilian bombshell Alessandra Ambrosio proved she's back in supermodel shape by showing of her flat stomach in L.A. on Monday ... four months after giving birth to her second child on May 7th.

The 31-year-old Victoria's Secret Angel has a lot in common with 32-year-old new mom Jessica Simpson ... as Alessandra had her baby just six days after Jess, who gave birth on May 1st.

Britney Spears had to endure the brutal Southern California heatwave yesterday as the singer-turned-judge taped several scenes for "X-Factor" in Malibu.

We're told Brit was on location in the Bu for two days braving the 100-degree heat that has been beating down on SoCal lately. She taped one-on-one segments with her chosen group of contestants ... where she decided who to keep and who to send home.

She may still be under an A-list conservatorship, but Britney Spears is definitely in charge of at least one thing ... making hysterical facial expressions on "The X Factor."

On last night's big premiere, the 30-year-old lip synching wonder's contorted eye, mouth and weave gestures said more about how she really felt about the contestants' performances than any of her actual critiques.

Although Britney's comments were surprisingly lucid, it was her awkward grimaces that stole the show.

The 27-year-old mother of one is very, very good for the environment.

Jessica Simpson says she's lost more than 40 POUNDS since giving birth to her baby 4 months ago.

Jessica revealed the weight loss number on Katie Couric's talk show today, claiming her weight loss surpassed the 40-pound mark ... but she wouldn't give an exact amount, saying, "It's not about the numbers."

Jessica also unveiled her new Weight Watchers commercial, shot two weeks ago. It's pretty funny because the commercial only focuses on Jessica's face. There is NO full body shot, which means WW probably wasn't too pleased with Jessica's weight loss numbers.

Jessica said, "I didn't want the big body reveal moment ... It wasn't me."

Sure.

Jessica Simpson ditched the frumpy clothing and lowered the giant handbag and let the world have a look at her new body as she went to lunch today with hubby Eric Johnson in New York City.

In her recent public outings, Jess has hid her bod under multiple layers of clothing and held her mammoth bag up close ... so no one could get a clean look before her big reveal today on Katie Couric's new show.

Looks like another Weight Watchers success story.

Jessica Simpson isn't ready to fully show off her new and possibly slimmer body ... going out in only non-revealing clothing and clutching a big bag close to her body.

TMZ posted pics of Jess earlier this week ... wearing multiple layers of clothing and holding a giant brown bag. Just this morning at LAX, Jess jetted out of town sporting a similar look, this time with a giant black bag.

Of course, Jess is no fool -- she's scheduled to appear on Katie Couric's new show this week to debut her slender, post-baby body ... so she's in no hurry to ruin that moment.

Clever girl.

Liberty Ross, still the wife of philandering director Rupert Sanders, flashed her toned gams at an Alexander Wang event for Fashion Week last night in New York.

The event featured such guests as Vogue Paris editor-in-chief Carine Roitfeld, Harper's Bazaar editor-in-chief Glenda Bailey, and Vogue senior editor Meredith Melling Burke.

Ross has been seen out several times since it became known her husband had an affair with "Twilight" star Kristen Stewart, whom he directed in the film, "Snow White and the Huntsman."

Jessica Simpson proved getting back to her pre-baby weight is a losing battle ... by showing off her slimmer figure after another workout in L.A. on Tuesday.

Jess has griped about how tough it's been to shed the poundage ... claiming her boobs are so tremendously huge, she can't go jogging.

Still, it's obvious the 32-year-old mom has made some progress in the four months since she gave birth to daughter Maxwell.
