Washington, Nov 19 Robert Pattinson had not realised the sway he and his words held on his audience until the Twilight hunk jokingly told a fan to strip - and she obliged him.

Pattinson made the revelation on Ellen DeGeneres' show.

He recalled that the incident took place "after a period of signing 500 signatures."

"You kind of get 10 seconds with each person and you never really say anything and I kind of got bored of saying, 'Hey, how are you doing?'" Pattinson tells the talk show host. "[A fan] said in her 10 seconds, 'What can I do to get your attention?' I was like um, just take your clothes off," People mag quoted Pattinson, as saying.

He said: "She stood there and frantically started taking her clothes off and got dragged out of the room by security."

He added: "I never felt more terrible." (ANI)
