Actor Alec Baldwin, star of TV show 30 Rock, married his fiancée, Hilaria Thomas, on Saturday in New York City, then posted a picture showing off his new wedding ring on Twitter.

Baldwin, 54, and yoga instructor Thomas, 28, announced their engagement back in April. The couple have been dating for over a year.

"Hilaria Thomas and Alec Baldwin were married this evening at St. Patrick's Old Cathedral in New York City, sharing the occasion with family and friends inside the Cathedral and Alec warmly receiving congratulations from well-wishing fans on his way into the service," Baldwin's friend and spokesman, Matthew Hiltzik, said in a statement.

Award-winning actor Baldwin, who plays egotistical television executive Jack Donaghy on popular sitcom 30 Rock, wore a Tom Ford suit while Thomas walked down the aisle in a dress by Amsale.
