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.

Little Red Riding Dame? The fabulous Helen Mirren had a not so fabulous fashion faux pas in Los Angeles, pulling a Britney Spears and baring her belly in a crop top. The 65-year-old star paired a loudly patterned skirt with red tights, shoes and sweatshirt, landing herself the worst look of the week.  See Helen here.
