Mariah Carey is not without flaws, as evidenced by the title of her new album “Confessions of an Imperfect Angel,” but her behavior on her current publicity tour is calling into question the veracity of the angelic claim as well.

“Her security is doing walk-throughs of her performance locations prior to her appearances, as if she’s the president or something,” said one person who was present at one such sweep.

It's even more intense on the day of a Carey performance, says the source. “She’ll show up with more than a dozen people on her team, and she’s been asking that the people who actually work there are removed from the floor and only her staffers be present,” said the source, who adds that the demand is not always met.

The level of high maintenance Carey is displaying while promoting both “Imperfect Angel” and her new film, “Precious”, didn’t surprise one person, who has worked with Carey in the past.

“We were paying for her travel, her expenses, and yet she still wanted to be compensated nearly six figures just for hair and makeup,” said the source. (Source: MSNBC)
