I guess Kellie is not as nice as what we imagined (at least I never like her), this article is very interesting http://tmz.aol.com/article2?id=20060222190809990001.
Here is the little scoop of it,
TMZ knows exactly where 'American Idol' contestants have been staying while in LA. It's a luxury hotel in Beverly Hills, though we won't say which one. We are privy to exactly what went on as contestants watched 'A.I.' together, hung out in the hotel's restaurant/bar and the VIP lounge, and even what they did in elevators. To say the least, it's amusing.
-- Kellie Pickler, who performed Tuesday, started out very nice, but the lowdown is that she's getting downright arrogant. Pickler told the chef, "You're lucky to be cooking for me." In fact, Pickler is so taken with herself that she belts out tunes in the hotel elevator.
