British soul star Joss Stone threw a massive temper tantrum moments before she was due to take to the stage on Saturday (27Oct07) - because her hair was dyed the wrong colour. The You Had Me singer, 20, was performing at the Desert Rhythm Festival in Dubai at the weekend when her hairstylist's attempt to colour her locks went drastically wrong. A source tells British newspaper The Sun, "Joss was screaming and sobbing because of this hair malfunction and chucked a tray of tea on the floor. "She wanted a little tint in her dyed red hair but it all turned dark blue. She was behaving like a woman possessed."
