Married of Alec Baldwin and Hilaria Thomas!

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.

Miley Cyrus birthday party

Miley Cyrus puts 'dope-smoking' controversy behind her stealing the spotlight in plunging yellow gown.

Just over a week ago she was fighting off controversy after joking she was a 'stoner' at her birthday party.

But if Miley Cyrus was affected by the uproar surrounding her 'gag' about smoking marijuana, she managed to put on a brave front at a charity event in Los Angeles last night.

The Hannah Montana star, who recently turned 19, looked all grown up as she slipped into a daring yellow gown for the CNN Heroes Awards Ceremony.
