T.R. Knight & his BF Mark Cornelsen had a date night last night when they went to see Righteous Kill at the Arclight Theater in Los Angeles, California. T.R. & Mark held hands and were all smiles as they headed to buy their tickets from the counter. They attended the same showing as Cindy Margolis! T.R. Knight wore jeans and a blue t-shirt and Mark Cornelsen wore jeans and a argyle patterned shirt. These two would definitely win any ‘Cutest Couple’ contest, if you ask us!
