Conan O'Brien officiated the first same-sex marriage on a late-night TV show last night.

It was the wedding of "CONAN" costume designer Scott Cronick and his partner David Gorshein.

Bravo's Andy Cohen walked Scott down the aisle on stage at the Beacon Theater.

"The wedding was performed while Conan is doing this week's shows in NYC because same sex weddings aren't legal in California," Susannah Breslin tells Boing Boing.

Their ceremony was in the Jewish tradition, via the Universal Life Church, of which I too am an ordained minister! The story of Conan's ordainment is here.
