Conan O'Brien is set to officiate over the wedding of a gay staffer, New York magazine's Vulture blog reported.

The 48-year-old O'Brien will tape his late-night talk show Conan at New York's Beacon Theater next week to celebrate the show's one-year anniversary on cabler TBS.

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.

“Show sources are quick to caution that the potentially groundbreaking event is no mere publicity stunt,” Vulture blogger Kyle Buchanan wrote, “and isn't intended too make light of gay marriage.”

No word on which show next week will include the gay nuptials.

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.
