Renée Zellweger stepped out in Milan today at the launch of Tommy Hilfiger's new, limited-edition handbag, which was designed to support Breast Health International. It was the actress's first public event since her split from Bradley Cooper was announced, and she looked chic in a red trenchcoat worn over a green dress as she arrived. Later, the Carolina Herrera spokesmodel changed into a strapless, purple number for a press conference to spotlight the new purse. Renée made her way to Italy for today's event after spending time among some famous friends as a guest at Reese Witherspoon's wedding less than two weeks ago.
