New York, Nov 6 : Cameron Diaz reportedly upset guests of her close friend Drew Barrymore’s lavish Halloween bash – by refusing to share her cigarettes.

Diaz spent most of the evening smoking along with many of the other guests but when approached by a couple for her cigarettes, the actress bluntly refused.

"Cameron was outside smoking the whole time, but when a couple of people asked if she had a cigarette, she always said no. It was so rude," the New York Post quoted a source, as saying.

Other famous faces who attended the Alfred Hitchcock-themed event included Britney Spears, Liv Tyler, Mary-Kate and Ashley Olsen and Eve. (ANI)
