BEST: Ciara had a hot date with Kim Kardashian at Mr Chow in Beverly Hills, clad in leather leggings, Christian Louboutin cutout booties and toting a Chanel bag.

BEST: Ashley Tisdale was a bohobabe, shopping in Beverly Hills, wearing a sheer shirt and cutoffs with oodles of bracelets and biker boots.

BEST: David Letterman was one haute host, terrifically trenched in Burberry in NYC.

WORST: Johnny Weir sported his ban.do headgear once again, wearing a Marc Jacobs ruffled blouse with a constructed suit. Leave the sparkles to Taylor Swift!

BEST: Rachel Bilson braved the NYC winds in an olive green Elizabeth and James trench with beige ankle boots, carrying a white Marni bag.

WORST: Agyness Deyn looked like a prison inmate—not a supermodel—strolling with her pooch in NYC.

BEST: Colin Farrell’s sexier half, Alicja Bachleda, attended the TriBeCa Film Festival premiere of Ondine, stealing the red carpet show in a pastel lilac Haider Ackerman gown from the Spring 2010 collection, adding gorgeously shimmering, strappy sandals.

WORST: Hofit Golan showed off her wacky style at the London premiere of The Back-Up Plan, wearing a cutout, swirl mini with white, Christian Louboutin booties.

WORST: Shenae Grimes attempted to copy Jessica Alba’s black boots-with-grey socks look, but pulled them up a little to high, resulting in an awkward look.

WORST: Sarah Jessica Parker went over the top with color, while out and about in NYC. Pink, red, purple, grey, and olive green are not a sexy color combo!

BEST: Mary J. Blige toted her Givenchy handbag around NYC, shimmering in a trench.

BEST: Kristen Bell was a sophisticated starlet at Dress for Success in NYC, wearing a black dress, which featured gold buttons.

BEST: Colin Farrell was pin-striped to perfection at the TriBeCa Film Festival premiere of Ondine.

BEST: Jessica Alba thought outside of the box when she chose this Jonathan Saunders Fall 2009 cocktail dress, but the color scheme really worked on her. Her biker jacket and Kris Can Assche boots were a flawless finish to the edgy look.

BEST: Jennifer Lopez had another style score at the London premiere of The Back-Up Plan, pairing a belted Lanvin one-sleeved dress with an attention-grabbing necklace, which was shown on the Spring 2010 runway. Still trying to figure out what is going on with that beehive, but oh well. Jimmy Choo heels finished off the look.
