After reports that she had split ways with her Thanksgiving-to-Christmas beau Jake Gyllenhaal, Taylor Swift rocked the red carpet of the People's Choice Awards in Los Angeles on Wednesday night, in fabulously fem fashion. The country cutie looked pretty in pink in a J. Mendel number from the Spring 2011 collection, which she paired with matching Prada heels and Neil Lane jewels. If she keeps looking this gorgeous, Tay Tay will surely find herself a new plus-one in time for the Grammy Awards in February.  See Taylor here.

Drew Barrymore missed the a la mode mark at the 50th Anniversary bash for CoverGirl. The brand's beautiful spokesperson looked great from the waist up in her marigold Jill Sander strapless gown from the Spring 2011 collection, but the cinched detail under her knees was unforgivable. See Drew's miss here.

Now that Winona Ryder is on the road to career comeback, the 1990's blockbuster babe should think about hiring a stylist! Wino hit the NYC premiere of The Black Swan dressed like a dude (more specifically like a gangster at a formal funeral) in a tuxedo-style Givenchy suit. Upping the style ante at the swanky screening was Mila Kunis, who showed off her bombshell body in a rosy Elie Saab gown, and Natalie Portman in an off-the-shoulder Christian Dior gown.

Reese Witherspoon got dressed in sophisticated style to receive her star on the Hollywood Walk of Fame.  The blonde beauty opted for a Dolce & Gabbana polka dot frock, which she perfectly paired with red heels.

At only 16 years-old, Dakota Fanning is quickly evolving into a style icon! While her underage peers are running around scantily clad in scandalous style (ahem, Taylor Momsen!) the Twilight star gets gowned in truly tasteful threads. Case in point. The blonde babe hit the 2010 BAFTA Britannia Awards in Los Angeles on Thursday night, looking absolutely angelic in a Valentino Haute Couture gown from the Fall 2010 collection, which featured a princess-worthy train and a bowed back. House hottie Olivia Wilde also looked fab in her designer duds, wearing a dark and dazzling Michael Kors ensemble.

Dynasty, redux. Joan Collins hit Beverly Hills old favorite Mr. Chow with scribe sis Jackie for dinner, pulling one of her trademark 1980’s sharp-shouldered blazers out of the closet. Though the 77-year-old star looked a tad outdated in the attention-grabber, she surely had Lady Gaga and Rihanna dialing up their stylists!  See Joan’s tacky Dynasty duds here.
