Making her debut at Cannes on Friday, Eva Longoria caused havoc at the prestigious La Plage Vitamin Water restaurant. While accompanied by her baseball player husband Tony Parker, the 34-year-old Desperate Housewife star demanded that the nearby private beach be closed so that they could enjoy their lunch in private. A source told the Daily Mail, “Eva insisted the staff put screens around her table to shield her from the crowds who had gathered to watch. Mariah Carey and Patricia Arquette were laughing at the fuss she made.” Eva, reportedly, touched nothing other than vitamin water.
