T.R. Knight Ducks Into Alcove

Grey’s Anatomy actor T.R Knight and boyfriend Mark Cornelsen run errands together in Los Angeles on Thursday.

The lovebirds first made a quick stop at the post office and then picked up some beverages at the natural food store.

T.R., 35, and Mark, 19, then shared breakfast at Californian/European style café and bakery Alcove Cafe in the trendy Los Feliz neighborhood.

After their meal together, Mark dropped T.R. off at a TV studio.
