Smiling through the pain?

Mariah Carey appeared upbeat for a night on the town in NYC on Tuesday, and from the looks of it you would never know that the Grammy winner and husband Nick Cannon are on the verge of a split. However, when we caught the father-of-two leaving his bachelor pad earlier in the day, it was definitely obvious something was up because he looked worse for wear. Maybe he's taking the marital stress harder than Mimi?

The America's Got Talent host let the cat out of the bag last week that there was "trouble in paradise" between the couple, and now the rumor mill is in overdrive about what caused friction with the former lovebirds. Some reports claim the songstress' recent album flop led her to release frustrations on her hubby. "When things don't go well career-wise, sometimes you turn on your other half. While she can be very down-to-earth and hilarious, she can also be high-maintenance," a source dished to People.

We're not sure what to believe, though, because the singer's father-in-law James Cannon insists she was the opposite of her diva persona. "Mariah was a beautiful part of our family. She was here at our home two weeks ago, talking and laughing with us all. I didnt see any problems between them. Everything was beautiful. Ive never seen them argue, fuss or go at each other. I see Mariah as an angel to our family and an angel to my son. I never saw Mariah as a diva, I love the way she handles herself. Shes a real talker and theres no snobbishness in her attitude, he told Page Six.

Guess we will have to wait and see what unfolds with these two!
