Pop superstar Mariah Carey has laughed off reports she ordered an assistant help her drink water at a recent album signing. During the London event, the WE BELONG TOGETHER singer was photographed drinking water from a glass held up to her mouth by an employee. The 36-year-old says, "That is so, ugh...I was at a record signing and I signed about 3,000 records. Most artists will go for maybe half and hour, then they leave everybody standing there. "I always feel guilty doing that, so I stay for a long time. I'm signing with one hand and shaking somebody else's hand, so someone tapped me to take a sip of water, and then they took a picture. "But believe me, I'd much rather hold my own glass! I can't even get a proper assistant, how am I gonna get a cup-holder?"
