Pattinson's guitar gift to a busker

He may be a vampire on screen but Twilight star Robert Pattinson s shown his generous side by handing a homeless Los Angeles street performer a guitar as a gift.

He donated a few dollars to the musician's collection tin but later returned with a new acoustic guitar for the busker. 

Pattinson's kind gesture was witnessed by holidaymaker Luke Jones, who told The Sun: "We were gobsmacked  when he handed the guitar to the tramp. 

"Robert quickly went back to his car and drove off. The busker was totally shell-shocked. He had no idea who Robert was -- I think he thought the guitar was stolen. He was looking left and right, half expecting the police to arrest him. We asked him to play but he couldn't get his thoughts together."
