Actor T.R. Knight has wed his boyfriend of three years in an intimate ceremony in New York. The 40 year old exchanged vows with his partner on Friday (04Oct13) in front of just a handful of guests, including his former Grey's Anatomy co-star Katherine Heigl, according to UsMagazine.com. Knight has yet to comment on the reports, but he was noticeably absent from his role as Mercutio in an off-Broadway production of Shakespeare's Romeo & Juliet on Friday and Saturday (05Oct13). A source tells the publication, "It (was) very small and quiet. (The) cast wishes they could go too, but they all congratulated him." Knight began dating his current partner after ending his two-year romance with Mark Cornelsen in 2009.
