"I'm married!" he Tweeted. "No more livin' in sin!"
Weir had discussed his wedding plans In an interview with IceNetwork.com on Dec. 29.
"His name is Victor [Voronov], he's kind of everything that I've ever looked for and aspired to be in a relationship with," the three-time U.S. champion and two-time Olympian said. "We've known each other for a long time and we reconnected over the summer, and it's just been a whirlwind. I'm very happy with my personal life and also my professional life, and I thank God I can be exactly where I'm at."
The 27-year-old publicly revealed he was gay in his autobiography Welcome To My World, which was released in January 2011 and excerpted in People magazine. He had previously avoided direct answers to questions about his sexuality in the press.
"I'm not ashamed to be me," wrote Weir. "More than anyone else I know, I love my life and accept myself. What's wrong with being unique? I am proud of everything that I am and will become."
In June 2011, Weir was given the honor of being the grand marshal of the Los Angeles PRIDE Parade, one of the largest LGBT celebrations in the United States.
Weir and Voronov tied the knot in New York, a state that legalized gay marriage in June. The newlyweds departed the Empire State on Monday for their honeymoon in the Dominican Republic.
