Top 20 Hilarious Celebrity Photobombs

17. Armie Hammer

Aaron Sorkin and Jesse Eisenberg were posing for a photo at the Golden Globe Awards in 2011 when they were photobombed by Armie Hammer. The Social Network co-star could not help but get into the picture and show Aaron and Jesse what a smile for the camera really looks like. His crazed expression and the fact that Aaron and Jesse are completely oblivious make this one of the funniest photobombs of the bunch.
