Alec Baldwin is moving in with his yoga instructor girlfriend.

The '30 Rock' star has sold his apartment in Manhattan, New York, to move into a new home in the city's SoHo district with his lover Hilaria Thomas, and friends reckon they could soon tie the knot.

A source told the New York Post newspaper: "He's really in love. He's even met her parents. He sees marriage in the near future."

Alec - who, at 53, is 26 years Hilaria's senior - were spotted wearing what appear to be promise rings at a charity softball game last weekend, and when asked if she sees marriage in their future, Hilaria was overhead saying: "Let's see how it goes."

Alec was previously married to actress Kim Basinger from 1993 to 2001. They have a 15-year-old daughter Ireland together.

Alec has been dating Hilaria since May this year, and it seems the actor had a change of heart about dating younger women.

Last year, he said: "What's worse than waking up with a 25-year-old woman, you know what I mean? You want to go shoot yourself because you have nothing to say to her. Seriously."

It is also rumoured Alec is to enrol in a master's program in politics and government in 2012, and that he one day has ambitions to run for the post of Mayor of New York.
