Conan O'Brien will officiate over the wedding of a gay staffer on the Thursday episode of his late-night talk show Conan on cabler TBS.

The 48-year-old O'Brien is taping his show at New York's Beacon Theater to celebrate the show's one-year anniversary.

O'Brien's former gig on NBC, Late Night with Conan O'Brien, filmed in New York City for 16 years.

The late-night host will highlight how things have changed in the Empire State during his absence by marrying a longtime gay staffer and his partner.

New York became the sixth state to legalize gay marriage in June and the law took effect the following month. Governor Andrew Cuomo has been widely credited with getting the legislation approved.

O'Brien was ordained through the Universal Life Church on October 21 to perform the legal ceremony. In a statement, the church said it “supports the rights of everyone in America to be married in a meaningful way and enjoy the legal, emotional and societal privileges that extend from matrimony.”
