Mariah Carey and Nick Cannon are getting into the Halloween spirit early. The new parents donned costumes from The Incredibles -- a movie about a family of superheros -- for a photo with their twins Morocco and Monroe.

The cute pic was part of a shoot Mariah did to benefit The Fresh Air Fund's Camp Mariah.

Mariah and Nick introduced the six-month-old twins to a national TV audience Friday night when they welcomed Barbara Walters into their home for an episode of ABC's 20/20.

During the interview Mariah revealed new details about her difficult pregnancy, including several false labors and gestational diabetes.

But with all of that behind them, Carey and Cannon say they are now just enjoying being parents.
