Seth MacFarlane is dating a mother ... of dragons!

The "Family Guy" creator, 38, has been spotted on a number of dates with 24-year-old "Game of Thrones" star Emilia Clarke.

Clake, who plays the very blonde Daenerys "Dany" Targaryen on the show, was seen hugging MacFarlane around the waist after a lunch date yesterday in L.A. -- and the couple was even seen smooching inside his car.

It's an interesting pairing, as the two have never worked together and are 14 years apart in age. Then again, Seth also reportedly dated Amanda Bynes back in 2008, so crazier things have happened!
