The secret to Neil Patrick Harris and David Burtka's romance is all in the voice—they sing to each other all the time.

In a visit with the ladies of The View, the couple shared a clip of them singing "Take Me or Leave Me" from Rent.

Additionally, they discussed relaunching Wigstock, one of the country's biggest drag queen extravaganzas. “We’re fans of drag as an idea,” said Harris, who won a Tony Award for Hedwig on Broadway in 2014. “I'm hypnotized by people who change their visage and guise and do it so well.”

“Drag queens are the spiritual leader of the gay community,” added Burtka, who came up with the idea of relaunching Wigstock last year while watching RuPaul's Drag Race. The festival, which had been on an extended hiatus, is a celebration of all things drag taking place Labor Day weekend in New York City.
