Nick Cannon, Mariah Carey Nick Cannon, Mariah Carey

The world already knew Mariah Carey and Nick Cannon had renewed their vows on their anniversary, as they have every year since marrying in 2008. This was, of course, despite her giving birth to twins Moroccan and Monroe  just hours before. But in our discussion with Cannon about his upcoming Showtime comedy special, Mr. Showbiz (Saturday, May 14 at 9/8c), he revealed that it was a ceremony complete with proper attire.

"We thought we probably weren't going to be able to do it, especially since my wife gave birth on our anniversary," Cannon tells "But she's a champ, man; she's superwoman. She pulled it off: Hours after giving birth she was in a wedding dress and a veil, exchanging vows. Not only do our children share a birthday, but we all share a day together. It's like Cannon Family Day. We're starting our own holiday. "

He also filled in details of playing Carey's music during her childbirth on April 30: "I was DJing her music. Our kids were born to her Fantasy performance at Madison Square Garden, so there was a big round of applause as the kids came out. She timed it that way."

She also continues to stay with the twins in a Los Angeles hospital since they're remain in the neonatal intensive-care unit, though Nick expects them to be home "Sunday/Monday-ish." In the meantime, they've taken over an entire wing of the undisclosed hospital. "I don't know how the hospital feels about that," he admits. "We got security standing at the elevator. It's crazy."
