Both stars wore Vera Wang (but of course!) and looked stunning with matching tanned legs (though Renee apparently opted not to spray her upper body, too).
Reese wore a bright violet satin strapless Vera Wang bubble dress, and Renee wore a strapless gathered maroon and black dress from the designer, as well as some Jimmy Choo Lance sandals.
Other stars in attendance included model Amber Valletta, "American Idol" judge Kara DioGuardi, Nicky Hilton, Angie Harmon, Maggie Grace, Mila Kunis, Lori Loughlin, and Kris Jenner, who was accompanied by husband Bruce Jenner.
