Gatecrasher reports: "It's splitsville for T.R. Knight and his boyfriend of two years. Just weeks after he said he wanted to adopt a child, the former 'Grey's Anatomy' star, 36, reportedly asked 20-year-old Mark Cornelsen to move out of the apartment they shared. 'It just came to a natural end, no hard feelings,' says a friend. 'They still care about each other very much.'"
