Seth MacFarlane and Alexis Knapp: Are They a New Couple?
08/16/2013 AT 09:10 AM EDT
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."
Before her breakout role in last year's Pitch Perfect (as Stacie, a highly sexual member of the all-female a cappella group the Bellas), Knapp, 24, was featured in Couple's Retreat, Percy Jackson & the Olympians: Lightning Thief and Project X. She will appear in the pilot of Rebel Wilson's new ABC sitcom, Super Fun Night", this fall.
Knapp might best be known, however, as the ex-girlfriend of Ryan Phillippe, with whom she has a 2-year-old daughter, Kailani.
Last year's Oscar host most recently dated Game of Thrones star Emilia Clarke, but that reportedly ended in March.
