Bar Refaeli knows that the best way to get over a break-up, is to get gorgeous!  The Israeli supermodel hit the French film fest in high style, hitting every premiere and soiree in designer duds to-die-for.  We LOVED every look that Leonardo DiCaprio’s supermodel ex galpal rocked, but her style high was achieved at the premiere of Mel Gibson’s latest flick The Beaver. The blonde beauty showed off every curve in a dark and dangerously tight Roberto Cavalli gown.

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.

It was almost impossible to pick the top look this week, as several sizzling stars were dressed in flawless fashion, but Jennifer Lopez slid into 1st place by a hair! The stunning superstar perfectly showed off her bombshell body at the 11th Annual Latin Grammy Awards in Las Vegas, wearing a magnificent metallic Andrew GN gown.  The sleeved wonder featured a plunging keyhole neckline, which accentuated her sexy top half, and was constructed out of body skimming material, which made the most of her covetable curves.

Cher has made it quite clear that she wishes she could Turn Back Time, but she needs to grasp the painful truth: she can’t!  The iconic singer, who is set to hit the big screen this month in Burlesque, has been busy promoting her flick all over the country, wearing faux pas fashions from the 1980’s and 90’s.  From her Late Show look of cutout leggings over fishnet tights paired with a belted sheer shirt---to her Glamour Women of the Year Awards Elvira ensemble---the Academy Award-winning “Goddess of Pop” was the Worst Dressed star of the week!

Style was not compromised at the 44th CMA Awards on Wednesday, as country music’s hottest crooners and big screen babes got all done up for the Nashville event. While Taylor Swift opted for a red hot Monique Lhuillier gown (see her here!) which featured a dangerously high slit, Gwyneth Paltrow showed some skin in a crafty cutout Atelier Versace one-shouldered number. And Nicole Kidman stood by her man, Keith Urban, thinking outside of the box by pairing her amazing Dolce & Gabbana white lace cocktail dress with cutout heels.

At only 16 years-old, Dakota Fanning is quickly evolving into a style icon!
