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 Stella McCartney Fall 2012 silk jumpsuit that featured sheer side panels. 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 Stella McCartney Spring 2012 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 head-to-toe Stella McCartney: a low-cut white top, dark gray jeans, a cotton  blazer and faux leather booties.

Other starlets who attended the West Hollywood bash include Kristen Stewart, Zooey Deschanel, Jane Fonda, Rumer Willis, Ginnifer Goodwin, Jordan Brewster, Pamela Anderson, Jayma Mays and Amy Smart.
