Mariah Carey was back to dressing like a teenager in St. Barth's with her adorable new pup Jack Jr. Guess she needed a little vacation after hitting the slopes in Aspen and hosting a NYE party. Mariah's displayed some high maintenance ways in the past, but at her NYE party, she claimed that she's anything but that. She said, "I've never done a diva-ish thing in my life. The definition of a diva is a woman who sings well, the second definition is a woman who's difficult to deal with. I hope I'm the first but I don't think I'm the second." Mariah may be more down-to-earth these days, but she should probably think back a little more before using the word never.
