Nick Cannon, phone home. The America's Got Talent host's superstar wife, Mariah Carey, just wouldn't let her hubby of three and a half years be for a minute as he lunched with business associates at the Chateau Marmont in West Hollywood on Dec. 13 — she called him more than 10 times in an hour!

Easygoing Nick, 31, began the outing by proudly showing off pictures of the pair's 8-month-old twins, Monroe and Moroccan. "He appeared to be having a great time, but his mood changed dramatically when Mariah started phoning him a lot," an observer tells Star.
