There Emma Stone was, minding her own business on the Oscars red carpet. Emma was just trying to oblige a member of the press with an interview when Justin Timberlake dropped an epic photobomb without her even noticing. It wasn't until he walked away that Emma turned her head and jokingly said, "Who are these people?" Justin, of course, was also on the red carpet with his wife, Jessica Biel, but hey, we're just glad he still had time to goof around. Check out the hilarious video above and, of course, the GIF below.
