Knight, 36, who came out in October 2006, met UCLA student Cornelson, now 20, at a Matthew Sheperd Foundation gala in L.A. in fall 2007. They began dating soon thereafter.

Last week, the actor confessed "I want a baby" on The Ellen DeGeneres Show. "I don't know if it's going to end up working out," he added, "but that would be something I would like."

In 2008, Knight told Us about Cornelson's rapport with his former TV cast."[One of my Grey's costars] in particular, I won't mention names told me, 'You know I like him more than I like you, right?'" he joked.
