Bradley Cooper refuses to reveal too much about his personal life because he's worried opening himself up to audiences will spoil their enjoyment of his movies. The actor of "The Hangover", who is reported to have split from girlfriend Renee Zellweger, has no plans to sign up to any social networking sites and admits he's baffled by stars who open up to fans online.
"It's a taste thing, I see the benefit of it [social networking] for sure," he tells Britain's OK! TV. "It's a great way to promote ideas and projects."
"For me, maybe I'm old fashioned, if I know so much about you and you're playing a character in a movie then that's a lot of work I'm gonna have to do to forget who you are so that I can believe the character and therefore enjoy the movie."
