Sundance: Nick Works, Mariah Lounges

A diva’s work is never done.

Mariah Carey has arrived in Park City, Utah, where she and husband Nick Cannon have his-and-her movies to promote.

Carey, above exiting her hotel, has been making rounds at the Sundance Film Festival pimping her flick Push. The 36-year-old portrays a social worker to a sexually abused pregnant teen, where as her 29-year-old hubby plays the subject of a deadly military experiment in The Killing Room.

While subject matter on both is serious, the pair are certainly enjoying the festival fun. Mariah and her man attended the opening night ceremony, the following morning Cannon hitting the Gatorade G Gym at Village at The Yard to train with Gunnar Peterson.
