Ugh, now I remember why I can't stand the twat and these other celebrities who have talent but have let their over-inflated egos take over! She's ridiculous!!!

Mariah's Sin City Demands?
Mariah Carey continues to set the standard by which all diva-licious behavior is measured. The Las Vegas Review-Journal claims the resurrected songbird was in classic high-maintenance mode during her weekend visit to Sin City.

Mariah reportedly requested not only the swankiest digs at the Venetian, but also asked for a $25,000 incentive to strike a pose on the red carpet at the opening of TAO, the hotel's new hotspot.

"She demanded blacked-out windows, the presidential suite, etc.," a snitch tells the paper.

Another mole tattles that Mariah was so determined to avoid eye contact with the little people during her stay that she asked for butlers and security staff to bow their noggins when graced with her magnificence.

The Review-Journal says she came up empty on most of her demands, failing to secure either the presidential suite (she got a penthouse) or the moolah, which prompted her to blow off TAO's celebrity-crammed opening on Saturday night, although she did attend Jermaine Dupri's birthday party at the club the night before. It remains unclear whether she was forced to meet the gaze of those far less fabulous.

This is just the latest report of demanding behavior from the fragile chanteuse, who earlier this year purportedly refused to step out of her limo until a London hotel had rolled out a red carpet and white candles for her middle-of-the-night arrival.

Meanwhile, in other Mariah news, she's firing back at rumors linking her to Eddie Murphy, whom she was supposedly spied "nuzzling" and holding hands with during the MTV VMA festivities in Miami last month.

"We were hanging out," Carey insists to People. "I'm a huge Eddie Murphy fan. Maybe they could just tell that, and that's why they made a big drama. But there is nothing going on. That's the last time I saw him."
