Only three months after announcing their engagement, Alec Baldwin and Hilaria Thomas have tied the knot.
The 30 Rock star, 54, and yoga instructor, who is at least 25 years his junior, wed on Saturday at St. Patrick’s Old Cathedral in New York, a friend of the couple’s confirms to PEOPLE.
The bride – who’ll now take Baldwin’s name – wore a silk magnolia trumpet Amsale gown with cap sleeves and a keyhole back neckline accented with crystal buttons.
Amsale also dressed Hilaria’s mother and Baldwin’s daughter Ireland. Baldwin had a tuxedo by Tom Ford.
Friend Matthew Hiltzik tells PEOPLE: “Hilaria Thomas and Alec Baldwin were married this evening at St. Patrick’s Old Cathedral in New York City with family and friends sharing in the joy of the occasion.”
The Rev. George Deas performed the ceremony, which was conducted in English with readings in Spanish (the bride grew up mostly in Spain), and guests included Baldwin’s costar Tina Fey and his brothers Stephen and Billy Baldwin.
Also attending were Woody Allen and wife Soon Yi, Mariska Hargitay, Robert Kennedy Jr. and Saturday Night Live producer Lorne Michaels.
The reception was set to take place in NYU’s Kimmel Center.
In the days leading up to the nuptials, the bride took to Twitter to share her excitement. “Being a bride is stressful…. ayyyyyyy,” she Tweeted Tuesday.
And it seems the planning went on up until the big day. “If I buy one bride magazine, which should it be?” she Tweeted Wednesday. And on Friday, she thanked the exercise program Physique57 for “making me bride ready, physically and mentally!”
Baldwin, who began dating Thomas last summer, has said that she is “very important” to him.
