Matthew Hiltzik, a friend of the couple, told ET, "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."

A-listers in attendance were Stephen Baldwin, Tina Fey, Mariska Hargitay, Robert Kennedy Jr., Saturday Night Live producer Lorne Michaels, Woody Allen and more. The groom wore a suit by Tom Ford, while the bride wore a silk magnolia trumpet Amsale gown, with cap sleeves and a keyhole back neckline, accented with crystal buttons.

This is the first wedding for Thomas, 28, and the second for 54-year-old Baldwin who was married to Kim Basinger until they divorced in 2002. Baldwin and Basinger have one daughter, Ireland, who also wore Amsale to the wedding.
