Bradley Cooper, Renee Zellweger Split

Just after the movie premiere: Limitless star Bradley Cooper and actress Renee Zellweger have broken up, sources said Saturday. As a couple, Cooper and Zellweger were tight-lipped about their relationship—in a recent interview, Cooper said “I just can’t” when asked about Zellweger. They dated for less than two years, having first worked together in the thriller Case 39 six years ago. On Monday, Howard Stern grilled Cooper about the relationship as Cooper denied any engagement plans.
