Uma Thurman and Andre Balazs Split

Uma Thurman and Andre Balazs have split up after dating for over two years. The Kill Bill star, 35, and property tycoon, 48, began dating in December 2003, only four months after the actress separated with ex-husband Ethan Hawke. After attending the Oscars on Sunday alone (the picture), Thurman confirmed speculation she was single again. A statement to the New York Post confirms, "Unfortunately it's true. But we remain close friends." In January, Thurman gushed about Balazs in interviews, declaring, "Everyone constantly taunts you that rebound relationships aren't a good idea and they don't work. But mine is working, surprisingly." Thurman has two children, Maya and Roan, from her six year marriage to Hawke and was previously married to English actor Gary Oldman.
