Kelly Osbourne was forced to back out of her final performance in West End musical Chicago, after she was hospitalised following a fall.
The 23-year-old was scheduled to perform at London's Cambridge Theatre on Nov 2 for the last of her performances as Mama Morton.
But, the singer has to call off after injuring her back in an incident on Oct 31.
Osbourne was taken to a London hospital and later released with a neck brace.
Meanwhile Kelly is keen to resume her Radio 1 Sunday Surgery and then film Project Catwalk for Sky One next month, after spending the weekend in bed.
