Top 21 Hilarious Celebrity Photobombs

7. Michael Cera

It is hard to decide whether it is funnier when celebs photobomb each other or when they photobomb regular people. This photo has Michael Cera smiling in the background as someone takes a picture posing with two parrots. Unfortunately, the parrots are no longer the stars of the photo because there is no looking away from the crazed expression on Michael Cera’s face. It must have been difficult for the person taking the photo to keep a straight face!
