Pop singer Lily Allen has posted a picture of a sick note from her doctor on her MySpace page to explain why she had to cancel tour dates.
Explaining her current condition, the singer wrote in a blog: "I've got sinusitis and strep throat (I don't even know what that is)".
Allen said that she had been told to take a couple of weeks off because her constant touring has caught up with her.
"Before anyone starts trying to accuse me of neglecting my fans I want to apologise and say how sorry I am, but I can't risk causing any permanent damage. I hope people can understand and aren't too angry," she wrote.
