The actor has ended his three-year romance with singer and actress, Charlyne Yi.
The split came just after the two began promoting their new film, Paper Heart, which opens in theatres on August 14.
It seems that Cera is interested in meeting new people, especially now that his career has taken off following his roles in Juno, Nick and Norah’s Infinite Playlist and Year One. "He’s been with her since before he was superfamous, and now all these girls fawn over him. He’s itching to date other people," a source told Star magazine.
However, the two stars will still have to work together to continue promoting Paper Heart.
