Robert Pattinson: I Have Trouble Thinking Before I Speak

Is Robert Pattinson shy? The 'Twilight' star offers fans everywhere a glimpse into his mind on Wednesday's "The Ellen DeGeneres Show."

On the program, Ellen comments that Rob seems more at ease acting than chatting on a talk show, and she says she thinks he might be shy.

"I just like doing things where you have a little time to think about what you're saying," Rob replies. "I've always had a problem actually thinking before I open my mouth."
