Lily Allen has to take good care of herself on tour - because she suffers from arthritis.
The 24-year-old singer admits a mild form of the condition, which affects her hands and knees, often leaves her in agony.
Allen suffered a nasty fall while she was on tour in August (09) and needed painkilling injections in order to carry on with the concerts.
And the star is convinced she had a lucky escape because the condition also means she is more susceptible to serious injury.
She tells Britain's Q magazine, "I've got mild arthritis in my hands and my knees. It runs in my family. My bones break very easily."
