Jessica Simpson gave birth to daughter Maxwell less than two months ago, and she's working hard to burn off the 60 pounds she gained during her pregnancy.

Jessica was spotted at the gym today for yet another private session with her trainer, and even though she's still got a ways to go before she'll fit back into her Dukes of Hazzard wardrobe, we're guessing that $4 million Weight Watchers contract is helping motivate her to shed the weight!

The 31-year-old singer/actress has been keeping a very low profile lately, but given how much time she's been spending working on her fitness, we're sure we'll see results in no time! I mean, wouldn't that be the best comeback EVER?

Today January Jones stepped out with her 9-month-old son Xander, and the Mad Men beauty showed off her newly dyed red locks. Since she added extensions to her hair, we're guessing the strawberry blonde hue is for a film role, but this still hasn't been confirmed.

So cute! We're still dying to know who the daddy is though!

After seeing Orlando Bloom in this tight black tank top, there's no question that he's packing heat. Check out those guns!

The daddy of one let his wavy brown hair go wild as he left the gym looking fit as a fiddle. Miranda Kerr is one lucky gal.

Bloom is set to star opposite Djimon Hounsou in the upcoming film Zulu which is set in post-apartheid South Africa. The flick, due to hit theaters in 2013, is about the murder of an 18-year-old girl ... which puts the spotlight on the Cape Town police department.

Perhaps the hunky actor is beefing up for the role!

Hilary Duff took her 3-month-old son Luca to the doctor's office this morning, and tomorrow she will appear on Bethenny Frankel's new show Bethenney, where she chats about motherhood and all that weight she gained during her first pregnancy.

When asked if she ate a lot, Duff replied, "Hell, yeah. I got down. More towards the end ... My whole life I’ve worked out and exercised and been in the public eye and always kind of watched what I ate. And this was like a free pass and it was a blast."

Duff added that she would "try not to gain as much weight" if and when she has baby number two, but she still wouldn't go back and change a thing.

Mr. Pixx

Dutch model Doutzen Kroes showed off her rockin' bod while hanging out poolside at the W Hotel in Miami with her hubby DJ Sunnery James and their 17-month-old son Phyllon Joy Gorre.

What a beautiful looking family!

Hard to believe Doutzen already looks fabulous in her bikini after just a little over a year since giving birth.

No doubt, she's been getting a daily workout chasing after her toddler!

Somebody's got to bring home the bacon!

Earlier today, Ryan Phillippe was spotted doing some grocery shopping with his son Deacon and girlfriend Paulina Slagter in West Hollywood.

The 37-year-old actor has been spending more time with his son since his ex Reese Witherspoon took off with their daughter Ava for her next project. He's got one of his own entitled Chronicle, where he'll star alongside Justin Long and Milla Jovovich in the crime thriller expected in theaters later this year. Wonder if Paulina will take care of the little one when Ryan's away?

Vanessa Hudgens and a gal pal went to Fryman Canyon in Studio City this morning, and the ladies worked up a sweat before the valley heat hit the low 80s this afternoon. Nessa went to the gym with her mom yesterday, so it looks like she's mixing it up when it comes to her workout routine.

The 23-year-old starlet doesn't have any new projects lined for next year, but she's chatted about breaking away from her squeaky clean Disney image and taking on edgier roles, like her character in the upcoming bank robbery flick Spring Breakers. She told the South African edition of Glamour Magazine in a recent interview, "I've been recently doing a few projects that are darker, deeper and heavier. Reading these situations in the movie where our characters rob people, which has such a harsh and hard element, was something that I just liked."
