Guthrie Theater alum and former "Grey's Anatomy" star T.R. Knight married his boyfriend of three years in New York over the weekend, People magazine reports.
Knight, 40, married Patrick Leahy in a ceremony Friday attended by his former "Grey's Anatomy" cast mates Katherine Heigl and Kate Walsh.
The actor starred as George O'Malley in the ABC drama series from 2005 to 2009.
A source told Us Weekly that that ceremony was "small and quiet."
Knight revealed he was gay in a statement released to People in 2006. In the statement, Knight said, "While I prefer to keep my personal life private, I hope the fact that I'm gay isn't the most interesting part of me."
The actor -- who returned to his hometown of Minneapolis in June to help the Guthrie Theater celebrate its 50th anniversary -- is currently starring as Mercutio in an off-Broadway version of the Shakespeare classic "Romeo & Juliet" in New York City.
Knight got his start in acting as a child with the plum role of Tiny Tim in a Guthrie production of "A Christmas Carol."
