Jessica Simpson

Jessica Simpson has yet to confirm that she's expecting a second baby, but the songstress did lose 50 pounds from her first pregnancy ... and now she's showing off her bod while shooting a new Weight Watchers ad.

The 32-year-old Fashion Star mentor and fiance Eric Johnson welcomed their daughter Maxwell Drew back in May.

In the new commercial, shot in the California desert a few months ago, Jess says:

"Weight Watchers changed my relationship with food, and I feel so much more prepared to make the right choices. It feels pretty incredible.”

As for whether her reported second pregnancy will affect her Weight Watchers commitment, time will tell.

After an 8pm performance of her Broadway play Dead Accounts, Katie Holmes headed out to celebrate her 34th birthday in New York City on Tuesday evening.

Earlier in the day Katie and her daughter Suri had breakfast at Sugar and Plumm, and on Monday the duo went to Georgetown Cupcake to make their own vanilla frosted treats for the actress' big day. "So much fun having Katie, Suri and friends for cupcake decorating," the bakery tweeted.

How sweet ... literally!

Kristen Stewart chats with the new issue of Newsweek magazine, and the 22-year-old Twilight actress still hates how famous she is, but she reveals that she doesn't really care what anyone thinks about her.

"It's not a terrible thing if you're either loved or hated," she told the publication. "But honestly, I don't care 'cause it doesn't keep me from doing my sh*t. And I apologize to everyone for making them so angry. It was not my intention."

"I was starting to get closed off and self-conscious, and I'm trudging forth into the world more often," Stewart said, seemingly referencing how she handled life after cheating on longtime beau Rob Pattinson with her married Snow White and the Huntsman director Rupert Sanders. "As long as people's perspective of me doesn't keep me from doing what I want to do, it doesn't matter," she added.

But if she's not popular and people don't like her, who's going to cast her in their movies?

He used to be in one of the hottest boy bands on the planet, and now A.J. McLean is the guy who wears tall Uggs with camouflage harem pants. Oh, how the mighty have fallen!

On Tuesday the former Backstreet Boy was spotted at L.A.X., and while his sense of style is making our heads spin, at least he was sweet enough to flash us the peace sign!

So what's A.J.'s life been like since the birth of his daughter Ava in late November? “She’s just everything to me,” the 34-year-old star told In Touch. “She’s changed my life ... It’s such a different feeling, being a father. Last night I was feeding her and I swear she smiled at me. That just about ripped my heart out.”

Ava is the first child for AJ and his wife Rochelle, who got married in December 2011.

She may have had a difficult time getting out of the car, but Amber Rose was in a great mood when we snapped her arriving at the dentist on Tuesday afternoon!

Fiance Wiz Khalifa dropped off his lady love, and we're not sure if she was coming or going from the gym, but we're def digging the hot pink workout clothes.

Amber tweeted a photo the other day of vanilla ice cream, chocolate sauce and strawberry pop tarts in a bowl and wrote, "The Pregnancy cravings r real ;-)," but it's not all sugar with Kanye's ex -- there's definitely plenty of spice too! "Never let any1 hold u back cuz of ur past become a better person & do better ... Prove them wrong. :-) ... Then u can casually tell ur haters 2 suck a fat Pork sword..... I do :-)." A pork sword!? Ha!

Gwen Stefani and husband Gavin Rossdale went holiday shopping in Beverly Hills and Studio City on Tuesday, and the No Doubt songstress was looking oh-so-chic in red leather pants and a houndstooth trench.

After a final stop at Barnes and Noble, the couple held hands and headed home to spend the rest of their day with sons Kingston and Zuma.

If we had Gwen's looks, wardrobe, family life and hunky hubby ... we'd be grinning, too!

Justin Theroux was spotted shopping at Helmut Lang in Beverly Hills on Tuesday afternoon, and while he wore his uniform of (mostly) all black, we couldn't help but notice how short his crewneck sweater was! Just think, if he hadn't been wearing a white tee underneath, we totally would have gotten a peek at his stomach! While Justin obviously has a great body, we have a feeling fiancee Jennifer Aniston wouldn't approve of this outfit...

Speaking of Jen, when are we going to see her baby bump again?

Hollywood detectives from the L.A.P.D. are investigating a hoax call at the home of Ashton Kutcher located on Arrowhead Drive.

According to L.A.P.D., officers were advised that there were individuals inside the location with guns and explosives, and that several people had been shot.

The on scene investigation determined the call was a hoax.

Hollywood detectives immediately launched an investigation to determine the origin of the call.

Their preliminary investigation revealed the call was a “swatting” incident, a term used to describe how computer hackers utilize their skills to place false emergency calls of serious crimes in progress to law enforcement and fire dispatch centers, thus causing a large number of first responders.

Ashton Kutcher's rep has yet to issue a statement.
