Which Star Looked Hottest at Paul McCartney's My Valentine Party?

Paul McCartney brought out some of Hollywood's biggest stars for the world premiere party for his "My Valentine" music video in West Hollywood Friday -- and each one of them donned stood out for very different reasons.

Singer Gwen Stefani, 42, showed off her perfect figure in an all-black ensemble that featured sheer side panels on both her peplum top and tight pants. The "Cool" singer completed her look with Christian Louboutin heels, a messy topknot and her signature red lip.

Supermodel Miranda Kerr, 28, went for an equally daring look in a Stella McCartney LBD that featured mesh panels on her left side. "I know Stella very well," the Australian beauty told Us Weekly. "It will be good to see her and catch up."

The evening also marked the first time Reese Witherspoon has appeared the red carpet since Us first broke the news of her pregnancy in mid-March. The This Means War actress, 37, donned a black shift dress with cutout details on the sleeves and skirt.

Oscar winner Gwyneth Paltrow, 39, was by far the most casually dressed of the night, wearing a low-cut! white t op, dark gray jeans, a fitted blazer and pointed black booties.
