Knight, alongside boyfriend Mark Cornelsen, acted as official witness to dozens of same-sex couples who tied the knot last night.

"There's a lot of hate around, and until that hate disappears, you're going to have people trying to push down another group of people for whatever reason," Knight said. He, however, did not take the plunge with his barely out of his teens boy-toy guy.

Just because you can, doesn't mean you should, eh, T.R.?

Obviously heeding the suggestion of his publicist, Jay Leno popped in for a brief appearance to express his "support."

Leno received plenty of flack back in March for a bizarre scenario on The Tonight Show in which he urged guest Ryan Phillippe to make his "gayest" face at the camera and subtly ridiculed one of Phillippe's first acting roles, when he played a gay teen on ABC's One Life to Live.

Phillippe, seemingly a little more aware of a public-relations disaster looming than the unfunny Leno was, declined to partake of the festivities.

Leno later publicly apologized for the incident and admitted it was "a dumb thing to say...I have friends in the gay community. Who doesn't know gay people in Hollywood?" he said, only half joking.

He's a card, that one.
