(LOS ANGELES) -- Family Guy creator Seth MacFarlane isn't a single guy. He's dating Pitch Perfect star Alexis Knapp, according to E! Online.
The website's source says, "It's been going on for a little while. It's very casual but they are hanging out and he is having fun with her."
The 24-year-old Knapp, who has a 2-year-old daughter with ex Ryan Phillippe, lent her voice to an episode of Family Guy last season.
MacFarlane, 39, was previously linked to Game of Thrones actress Emilia Clarke.
