Looks like T.R. Knight is off the market.

The Emmy-nominated Grey's Anatomy star, who plays George O'Malley, stepped out with boyfriend Mark Cornelsen during the 2008 Elton John AIDS Foundation Oscar Party held at the Pacific Design Center in West Hollywood on Sunday.

The two held hands and looked very happy together. See below:

Grey's Anatomy Quotes

Meredith: You're me.
Amelia: What?
Meredith: You're me before Derek. I can be here for you. I can do this. I get you. I can be a twisted sister for you. Just tell me how do you want to play this?

Did you say it? 'I love you. I don't ever want to live without you. You changed my life.' Did you say it? Make a plan. Set a goal. Work toward it, but every now and then, look around; Drink it in 'cause this is it. It might all be gone tomorrow."
