George Clooney photobombs Jerry Seinfeld and Steven Spielberg

We always thought George Clooney was quite slick, now we know it for sure

This is a photobomb that's so stuffed full of famous people that we're not really sure where to start, but we'll give it a go anyway. It seems that Clooney, Spielberg, Seinfeld and his wife were all in attendance at a gala ball on Thursday night in New York, when George, a notorious A-list prankster, saw his opportunity to strike, photobombing the unsuspecting trio.

Hollywood stars must be trembling with fear as they wonder will be next on Clooney's prank list after seeing this.
