Family Guy creator Seth MacFarlane looks like he has a new lady in his life, and it's not cartoon wife Lois Griffin.
MacFarlane, 39, has been dating Pitch Perfect actress Alexis Knapp, E! News reports. Knapp's voice – coincidentally – could be heard on the "Valentine's Day in Quahog" episode of MacFarlane's hit FOX show this past season.
"They've known each other and have been friends for years," a source tells PEOPLE. "She's very bright and loves science like him. She's down-to-earth and sweet."
