In an interview on the Gayle King Show, Nick describes the birth as "a production", during which he was "the production manager".
With a camera in one hand and using the other to "play DJ", the couple made sure the newborn children were welcomed into the world by the best music on Earth: Mariah Carey music! LOLz!
"My wife wanted to make sure when the babies came out that they came out, not only to a Mariah Carey song, but a live performance from Mariah Carey."
No, she wasn't able to belt out all of her hits in the midst of pushing two babies out, but apparently Nick played a recording of a concert at Madison Square Garden.
Watch the interview above to get the full story from Nick!
Do U think that sounds like they went a little overboard or was it cute?
