Alec Baldwin is a marrying man -- again! The 30 Rock star, 54, and his girlfriend, yoga instructor Hilaria Thomas, 27, exchanged vows at St. Patrick's Old Cathedral in Manhattan on June 30. Dressed in a tuxedo by Tom Ford, the multiple Emmy winner and his love (who has already changed her name to Baldwin on Twitter), who wore a silk and crystal Amsale gown, said their "I dos" in front of their friends and family, starting with the groom's mother Carol Baldwin and actor brothers Stephen and Billy Baldwin. Celebrity guests in attendance included costar Tina Fey, director Woody Allen, actress Mariska Hargitay, environmental activist Robert Kennedy Jr. and Saturday Night Live producer Lorne Michaels. The newly minted Mr. and Mrs. Baldwin celebrated their nuptials with a reception atop New York University's Kimmel Center. The social media-savvy husband and wife shared photos of their wedding rings, with Hilaria proclaiming Sunday morning: "I'm so happy"
