Robert Pattinson Support Tsunami Relief

Taking it off for a worthy cause, Robert Pattinson stripped out of his t-shirt to sign and auction it off in support of Japanese tsunami relief.

The kind-hearted Twilight" hottie donated his top to the Yoshiki Foundation, which uses the proceeds to help those affected by the massive disaster.

Robert is the latest to join a slew of Hollywood do-gooders who have offered up their support through donations and autographed materials.

Other charitable celebs include James Franco, comic legend Stan Lee and Pattinson's "Water For Elephants" co-star Reese Witherspoon.
