Seth MacFarlane Dating Ryan Phillippe's Babymomma Alexis Knapp! New Couple Alert!

Pop quiz: What do Seth MacFarlane and Ryan Phillippe have in common?

If you guessed “an impressive set of manly eyebrows,” you’re waaaaay off base… but we like your thinking!!

It’s Pitch Perfect star Alexis Knapp!

Alexis and Ryan are connected by their daughter, a two-year-old gift from the heavens named Kai.

Seth and Alexis — a.k.a. Hollywood’s freshest couple — are connected by, well, whatever happens in the privacy of their bedroom is their business. Either way, we just learned the former Oscars host and the 24-year-old beauty recently became intimately involved!!!

A source close to NEW COUPLE reveals:

“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… They’ve know each other for three years and have been getting closer for over a year… They always had good chemistry… Alexis’ star is on the rise… He thinks she’s really talented.”

Oooh! Good for them!!!

We hope Seth’s ex-gal pal Emilia Clarke is OK with his impressive rebound!

You know what they say, hell hath no fury like the Queen of Dragons scorned!!!

Do U think Alexis and Seth are a great match?

Will their burgeoning romance stand the test of time? More importantly, should their exes Ryan and Emilia sit next to each other at the wedding?? LOLz!!
