"Paula has been out of control on the set [of her new show "Live to Dance"]," disclosed a show insider. "Her favorite phrase is ‘I’m not happy’ -- and she’s not happy a lot. She started with the food in her dressing room. When she didn’t see her favorite Jolly Rancher candies -- she hit the roof. And when she had to go searching for Vitaminwater, she complained bitterly, saying she wasn’t getting the respect she deserved."

According to the insider, at a recent promo shoot, Paula kept everyone waiting while she changed her clothes several times because she thought they didn’t fit right. "Finally, after six or seven changes, she gave her approval to be photographed, but she still wasn’t thrilled," said the insider. "She’s been driving everyone else on the show crazy!"
