I know what you’re thinking and no, it wasn’t on the set of Little Ashes. Rather, it was during filming of Twilight that accident prone Robert Pattinson received an embarrassing injury. The big screen vampire strained his butt muscle while hoisting his costar Kristen Stewart into the air.

As humiliating as that might have been, Robert had no problem confessing, “I got injured on the first shot of my first day on Twilight. I lifted Kristen and ripped my arse cheek. I had to get a bum massage for the cheek.” Ooh, so is that how one goes about fenagling an ass massage?

Meanwhile, here are all the stars of Twilight going twinkle, twinkle in a Japanese magazine.
