T.R. Knight has split from Mark Cornelson, his boyfriend of two years, PEOPLE has confirmed.

“It’s amicable,” says a source of the breakup.

Don’t expect the newly single actor, who departed Grey’s Anatomy this spring after five seasons on the show, to be spending his nights nursing a broken heart at home: He’ll be performing in Parade, his first musical, in Los Angeles through Nov. 15.

The split was first reported by In Touch.
