The '30 Rock' star was resigned to leading an "unhappy" life alone before he met Hilaria, who he has been dating since last March.
He told TV talk show host Piers Morgan: "It is true what people always say, and it's tough to make your way to that place, I guess, where you stop looking.

I'm gonna be alone for the rest of my life, I'm gonna die alone in this apartment in this bed, I'll have my friends, I'll have twitter, I'll have Words with Friends, I'll have my New Yorker subscription... I'll have my quiet, unhappy life', and then right when I put it all on the shelf, and it was over I walked into a restaurant and I met this woman who is probably one of the greatest people I've ever met in my life."
