Sharon Osbourne has been forced to pull out of filming the auditions for this year's X Factor.
The 64 year old is recovering from a back injury and will be temporarily replaced by Britain's Got Talent judge, Alesha Dixon.
An X Factor spokeswoman told that, "Sharon is suffering from niggling back problems following surgery earlier in the year and will be unable to take part in the Edinburgh auditions."
Sharon was set to judge the Edinburgh alongside Louis Walsh, Nicole Scherzinger and Simon Cowell but Alesha was recruited at the last minute.
Earlier this year, Sharon Osbourne revealed she had hurt her back while playing with her grandchildren and she's reportedly been flown back to Los Angeles to consult her doctor.
