Seth MacFarlane is being linked to model and actress Alexis Knapp after also being linked two years ago. She has since had actor Ryan Phillippe’s baby.

Knapp’s voice was featured on an episode of MacFarlane’s Family Guy this past season and sources say they’re casually dating.

"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," a source told E! News.

The insider added, "They've know each other for three years and have been getting closer for over a year. They always had good chemistry."

Knapp, 24, had a breakout role in Pitch Perfect and has also been featured in films Couple’s Retreat, Project X, Percy Jackson & the Olympiansn: Lightning Thief and this fall she will be featured on Rebel Wilson’s show Super Fun Night.

Digital Spy notes MacFarlane most recently dated Game of Thrones’ Emilia Clarke and he was linked to Oscar winner Charlize Theron earlier this year, but she brushed off the rumors, saying they were only good friends.
