While attending a live comedy show, the “No on H8 show” at The Improv in Hollywood a few weeks back, Robert Pattinson reportedly took offense to a rude comic’s joke on Heath Ledger.

According to reports, the 22-year-old Twilight megastar booed a comedian who said, “Here’s my impression of Heath Ledger,” before falling to the ground while faking convulsions. Other people from the show said,  “Robert and his friend went nuts yelling at him. “[Pattinson screamed] f–k you! You suck!”

As though prone to boos and shouts, the comic failed to recognize that he was being booed by the world’s most famous young star right now.

Pattinson seems like a bad boy with his latest Vampire role and grunge look, but deep down, he’s just a guy who knows how to stand up for what’s right. I guess this just gives Twilight fans another reason to love Rob…
