BEST: R&B star Omarion put the hip into hop in a leather vest and black Lakers cap when he met a young fan through the Make A Wish foundation at the Westfield Mall in Culver City, California.

BEST: Jessica Alba kept it effortlessly casual as she enjoyed a Sunday fun day at a charity event with her daughter, but it was Honor’s tiny yellow Converse that really brightened up the outing!

BEST: Ashlee Simpson may be a mom now but she’s not left her hippy roots behind her. The pale-skinned star hid from the sun under a floppy hat and big shades as she took baby Bronx to a birthday party on Saturday.

BEST: Kate Hudson kept dry under a wool stylish hoodie as she braved the wind and rain during a drizzly London afternoon, but the actress should have ditched the big “I’m a celebrity” shades as there were very few rays of sun escaping through the clouds.

BEST: Zoey 101 star Victoria Justice was ready for school Hollywood-style in skinny Guess Riding Leggings, Guess plaid blazer and Alexander Wang Freja Laced Zip Booties, as she hosted Macy`s Kicks Off Back-to-School with Nickelodeon in New York City.

WORST: Sharon Stone was more stressed out mom than Hollywood bombshell as she took her kids out for pizza in Beverly Hills at the weekend. Her brightly dressed sons win more style points than this former fashionista!

BEST: After landing more “Worst Dressed” awards than movie roles in recent years, Mischa Barton looked surprisingly put together with sleek, straightened hair, baggy shorts and leather wedges as she filmed Fearne Cotton’s new reality show for British TV in Los Angeles.

WORST: It was all shades of grey as Sean Penn lunched with U2’s Bono the day after his 50th birthday.

BEST: Up In The Air star Anna Kendrick looked like a real business executive in a fitted skirt and blouse as she left a Dublin hotel to promote her new film, Scott Pilgrim Vs The World. All she needs is a briefcase or a laptop bag and she’d be all set for a professional power lunch!

BEST: Has Bradley Cooper been getting red carpet style tips from Renee? The hunky actor looked sexily slick in a pastel suit at the Tokyo premiere for The A-Team.

BEST: Ugly Betty star America Ferrera had ruffles in all the right places at the Imagen Awards in Los Angeles on Sunday, in a Catherine Malandrino dress with Christian Louboutin shoes and Old Hollywood earrings by Kara Ackerman Designs.

WORST: After having rocks and other objects thrown at her while on stage during a concert in Illinois, Tila Tequila hid her bruises under giant Yoko Ono style shades as she landed at Los Angeles International Airport.

WORST: While we love America’s Next Top Model winner Krista White’s black and white mini and endless legs, but her blue suede booties look like Smurf shoes! Strappy sandals would have been a much better choice.

WORST: Just like her dad’s music, Alexa Ray Joel’s style is stuck in the 70s. Billy’s daughter needs to ditch the high-waisted shorts and knotted shirt if she ever wants a fashion hit.
