Joss StoneJoss Stone was reportedly livid when her hair was accidentally dyed the wrong colour just moments before a gig in Dubai at the weekend.

Joss was set to take to the stage at the Desert Rhythm Festival on Saturday when she decided to wanted her already dyed red hair livened up with some blue streaks.

A source told the Sun: “She wanted a little tint in her dyed red hair but it all turned dark blue.”

“Joss was screaming and sobbing because of this hair malfunction and chucked a tray of tea on the floor.”

“Then when she walked in front of the crowd she had a beaming smile and acted like nothing had happened.”

But the colour looks like it might have grown on the singer - she had the same deep blue colouring when she performed at the Angel Ball in New York on Monday night.
