British soul star Joss Stone banned photographers from taking her picture at Henson Studios 9th Annual Friends + Family event in Hollywood last night (06JAN06) - because she had a coldsore.

The self-conscious star tried to mask the blemish but when she found she couldn't she advised her publicist not to let photographers snap her.

One bystander at the party, which also featured Nick Carter, Benji Madden and Avril Lavigne, said, "You could only notice it (the coldsore) if you went right up to Joss.

"Her publicist was literally running around at the party trying to stop any photographer from snapping her."
