Alec Baldwin marries Hilaria Thomas in an opulent ceremony in New York

Alec Baldwin and Hilaria Thomas tied the knot in an opulent ceremony at one of New York’s most magnificent cathedrals.

Alec Baldwin, 54, and yoga instructor Hilaria Thomas, 28, said “I do”, Saturday afternoon.

The bride – who will now be known as Hilaria Baldwin – wore a silk magnolia trumpet Amsale gown with cap sleeves and a keyhole back neckline accented with crystal buttons.

The bridesmaids wore “eclectic miss-matched dresses, some in black, gray and turquoise, others in bold turquoise-and-purple tie-dyish prints”, according to E! online.

Amsale also dressed Hilaria Thomas’ mother and Alec Baldwin’s daughter Ireland.

Alec Baldwin had a tuxedo by Tom Ford, People magazine has reported.

The Reverend George Deas is said to have performed the ceremony, reportedly conducted in English with readings in Spanish.

Guests at the nuptials in Manhattan’s Nolita district included Alec Baldwin’s 30 Rock co-star Tina Fey, his brothers Stephen and Billy Baldwin, Woody Allen and wife Soon-Yi, actress Mariska Hargitay, Robert Kennedy Jr. and Saturday Night Live producer Lorne Michaels.

After the ceremony, guests were filtered to the campus of Hilaria’s alma mater, New York University, for a reception at the private school’s nearby Kimmel Center.

Earlier Hilaria tweeted: “Today is going to be a good day.”

According to E! Online the couple chose a white color scheme for the ceremony, highlighted in the selection of flowers that decorated the historic cathedral.

Florist De Juan Stroud placed “white hydrangeas, white roses and calla lilies around the church”.

The entertainment website also reports that white ribbons were tied to the pews and a tent was set up near the back entrance of the church.

Alec Baldwin, who is 26 years Hilaria’s senior, asked for her hand in April in Long Island, New York.

The two dated for almost a year before he proposed and they first appeared in public together at several bashes in New York in May 2011.

Alec Baldwinwas previously married to Ireland’s mother, Kim Basinger, but the pair divorced in acrimony in 2002 after nine years of marriage.

Spanish-born Hilaria Thomas has not been married before.

She grew up between Boston and Spain, studying dance and history at NYU before becoming a yoga instructor.

In recent months Alec Baldwin has been sporting a noticeably trimmer physique, perhaps in a bid to appear more youthful alongside his younger partner.

The actor is apparently planning a very laid back summer with his new bride.

Taking to Twitter again before the ceremony, he revealed the couple could be off to Kingston, Idaho for their honeymoon.

Accompanied by a scenic picture of the Coeur D’ Alene River, Alec Baldwin wrote: “I can’t wait to stand on these rocks at Albert’s Landing and leave this world behind…. for the Summer.”
