Pattinson rips comic over Heath impression

LOS ANGELES, Dec. 30 (UPI) -- British actor Robert Pattinson booed and yelled at a comedian who poked fun of Australian actor Heath Ledger's death, a source told Usmagazine.com.

Ledger died in January of an accidental prescription drug overdose at the age of 28.

Usmagazine.com said Pattinson, the star of the vampire blockbuster "Twilight," was in the audience of a show at The ­Improv in Hollywood Dec. 16, when a performer reportedly said, "Here's my impression of Heath Ledger," then collapsed into pretend convulsions.

"Robert and his friend went nuts yelling at him," a source told the magazine, adding that Pattinson screamed: "(Expletive) you! You suck!"

"The comic didn't know who it was, but I'm sure he found out later!" the insider said.

The magazine did not offer the name of the performer.
