The creator of "Family Guy" may have found his own future Lois Griffin. Seth MacFarlane, who also voices many of the show's characters, is dating "Game of Thrones" actress Emilia Clarke, according to Us Weekly.

A source told the magazine, "It's been going on for a few months."

The pair hung out Sunday at HBO's Emmy Awards after party and reportedly left at the same time. One day earlier, MacFarlane, 38, and Clarke, 25, were spotted leaving the Four Seasons Hotel in Beverly Hills. On Tuesday, they were arm-in-arm leaving a restaurant.

The source told Us Weekly MacFarlane "wants someone he is attracted to but who can have a good time and enjoy his success with." The source also described MacFarlane as a "Game of Thrones fan." Clarke plays exiled queen and dragon tamer Daenerys Targaryen on the hit HBO drama.

Reps for MacFarlane and Clarke did not immediately respond to ABCNews.com's requests for comment.
