T.R. Knight of "Grey's Anatomy" fame has tied the knot with his longtime boyfriend, according to a report out Monday.

Knight did the deed in a "small and quiet" ceremony in front of friends and family on Friday, a source told Us Weekly. His beloved was identified in the report only as "Patrick."

In attendance was his former "Grey's" costar Katherine Heigl, who reportedly flew in for the occasion. Knight left the ABC show in 2009, with Heigl departing in 2010.

He's currently appearing as Mercutio in an off-Broadway production of "Romeo & Juliet," Us reported, but missed shows Friday and Saturday.

Prior to dating Patrick, Knight was in a relationship with student Mark Cornelson, who was 16 years his junior. When he was dating Cornelson, he told People he was open to the idea of adopting children.
