Heigl and Knight, 40, worked together on the show from 2005 to 2009, with the openly gay star earning an Emmy nomination in 2007 for Outstanding Supporting Actor.

After leaving the show, Knight took to theater, including "Parade" in Los Angeles and David Mamet's "A Life in the Theatre" on Broadway in 2010. This past year, he's taken on the role of Mercutio off-Broadway in "Romeo & Juliet."
