Mariah got stood up!

Singer Mariah Carey had a tough time with celebrity hairstylist Ricardo Rojas during her trip to the Cannes Film Festival, it has emerged.

“He came highly recommended and travelled with her for a few weeks.   At one point, Mariah, who went to beauty school, was unhappy with her hair and was showing him how she liked it. It seemed to have not gone over too well and he didn't show up the morning of her press conference and premiere of her new film Precious,” the New York Post quoted a source as saying.

Following the trip, the 39-year-old songstress has decided not to use Rojas again after he left her on the day of the premiere of her new film without informing her.
