Alex Pettyfer & Dianna Agron are Hot Topics

Alex Pettyfer and Dianna Agron keep cozy as they attend an I Am Number Four signing event held at Hot Topic in San Bruno, Calif., on Saturday night (January 29).

Some fans at the signing were also treated to a free screening of the flick — which hits theaters on February 18th.

I Am Number Four is a story about a group of nine earthbound aliens who escaped their planet just before it was annihilated by a rival species. Hiding out on Earth, disguised as a human teenager in high school, the title character discovers that he is being hunted by the enemy that destroyed his planet.
