Why? It all started with that fake American accent she came out with at this year's Brits, and the less said about that frizzy 80s barnet - dyed student-away-from-home-and-rebelling-against middle-class-parents red, for goodness sake - the better. Oh and saying, "I've had four [managers] in the past five years and I hate them all" - her mum Wendy used to manage her, by the way - is hardly endearing. But the news of Joss Stone's latest tantrum backstage at Desert Rhythm has really pushed us over the edge.

"She wanted a little tint in her dyed red hair, but it all turned dark blue," a source told The Sun. "Joss was screaming and sobbing... and chucked a tray of tea on the floor. She was behaving like a woman possessed."

Yeah, possessed of zero taste in hairdos.
