Rosie Huntington-Whiteley makes a living off her looks, so it's no surprise she's so dedicated to her fitness routine!

The Victoria's Secret stunner looked incognito arriving at a private LA gym in all black workout gear and a NY Yankees hat, but there's no mistaking her with that unbelievable body. We would kill for those legs!

The 24-year-old model recently revealed she felt bullied by industry big wigs when she started out in the fashion industry, but things have gradually improved over the years.

"The last couple years, things have been different. I have earned a right to be heard. All I ever wanted to do was to be part of the industry, to collaborate with people and to have a voice. I love fashion, I love what I do and I have an opinion... they treat me like I'm part of the family, not just some clothes hanger," she explained to The Guardian Weekend magazine.

You go girl! Way to earn that R-E-S-P-E-C-T!

Shenae Grimes is such a natural beauty, so we're going to excuse this frumpy outfit...

The 90210 star arrived on set Tuesday looking ready for bed - not ready to work! She kept it a little too casual in sweats, a tank top, and slippers, but we're guessing she headed straight to the wardrobe trailer to get camera-ready!

The 22-year-old actress is usually such a trendsetter... she recently even turned her personal website into a fashion forum to get interactive with her fans!

"I'm going to be uploading pics of my every day outfits for those interested, if you have any questions or comments about styles you see, would looove to hear your feedback!" she wrote on her blog March 9.

We bet her fans didn't love this look either!

Why so shy, Biebs?

We caught Justin Bieber leaving a dance class in Hollywood on Tuesday, and he didn't want to give us a glimpse of his pretty face... maybe he wasn't looking camera-ready?

We hope the teen sensation is choreographing some new moves to accompany his upcoming single "Boyfriend", which drops March 26.

As if music, dancing, and romancing Selena Gomez wasn't keeping him busy enough, the Canadian pop star will also be appearing on the re-vamped version of MTV's Punk'd, debuting on March 29.

The "Baby" singer must be getting excited for everyone to see his silly side! He tweeted at show creator Ashton Kutcher:

@aplusk i think the world is ready for us. #prankstersontheloose

Uh oh! We can't wait to see what Justin has in his bag of tricks!

Alanis Morissette and hubby Mario "MC Souleye" Treadway have a new walker in the family!

Their 1-year-old adorable son Ever is already making strides ... literally. Look at him go!

The little cutie, who was rocking a striped tee, red pants and a beanie, looks so much like his rapper daddy. Perhaps he'll grow up to have his mom's powerful vocals.

One step at a time!

Mischa Barton dined at Il Sole with her mom last night, and the 26-year-old actress is looking better than ever! Earlier in the evening the former OC starlet hosted the LA store opening of the Japanese fashion house Growze, and not only does she look great in their clothes, but it seems like her decision to hire stylist June Ambrose is paying off as well.

The actress also showed off a tote from her Mischa Barton handbag line, and she chatted with CelebStyle about her expansion into accessories and clothing. "I've always had a serious love of fashion, and it all started with my handbag line," she tells the site. "This current clothing and accessories line has a fun, youthful vibe." Can't wait to see more of it!

Jessica Biel has signed on to join Scarlett Johansson in the upcoming horror flick Making of Psycho, according to Deadline.

Biel, who reportedly is now engaged to Justin Timberlake, will play Vera Miles ... the character who discovers Mrs. Bates' bones.

Johansson, 27, will star as Marion Crane which was the role famously played by Janet Leigh in the original 1960 thriller.

Other actors that have signed on to the Alfred Hitchcock film include Anthony Hopkins, Helen Mirren and James D'Arcy.

Jennifer Lawrence and her Hunger Games co-star Josh Hutcherson attended a special signing event at Barnes & Noble in New York City last night, and hundreds of fans lined up for their chance to meet the stars. The movie hits theaters on Friday, but we have a feeling the craziness will only continue to grow once we get our first peek at Katniss, Gale and Peeta on the big screen!

Jennifer posed for a few shots with Josh, and no offense to Vanessa Hudgens' former flame, but Jen absolutely stole the show in this low-cut green Calvin Klein Collection frock:

Madonna has released the music video for "Girl Gone Wild" and the 53-year-old singer still has all the moves -- and plenty of ways to get critics talking!
