Top 21 Hilarious Celebrity Photobombs

10. George Clooney

George Clooney cannot help but steal the show in this picture of Jerry Seinfeld, Jessica Seinfeld, and Steven Spielberg at the USC Shoah Foundation Institute 2013 Ambassadors for Humanity gala. The photo is amazing, even without George Clooney, because of the talented stars. But the addition of the silly face of George Clooney in the background propels it to a whole new level of awesome. Watch out for those crazy eyes!
