T.R. Knight says he's not marrying his boyfriend...

All we have to do is look at pictures of TR Knight and his cutie pie boyfriend Mark Cornelson to see that they are crazy about each other. But the "Grey's Anatomy" star told US Weekly that they are not ready to exchange vows:

"To clarify, we are not having a commitment ceremony," TR said. "once you are given something that you were never allowed before, you realize how much of a second class person you were before. That is horrible and fantastic at the same time. It makes me want to sob and scream with joy all at the same time."
