Jason Segel plaid shirt jfk airport

We guess work was calling him back to L.A.!

Jason Segel departed JFK airport Sunday after spending quality time with girlfriend Michelle Williams and her daughter Matilda in the Big Apple, and the How I Met Your Mother star seemed in a cheery mood despite having to leave his ladies behind!

The A-list couple recently returned from a Mexican vacation with the Oscar-nominated actress's pal Busy Phillips, and even though they were accompanied by friends, we were kind of expecting the blonde beauty to come back from the holiday with a ring on her finger. The I Love You, Man actor seems to have found The One in the Dawson's Creek star, and has assumed the role of father figure in her little girl's life.

We think it's only a matter of time before we hear wedding bells!
