She’s been a singer, a reality star, even a reality show host, and now Kelly Osbourne is going to try the theater on for size. The 22-year-old daughter of Ozzy will play Mama Morton for seven weeks at London’s Cambridge Theater, beginning this fall. Kelly’s famous father was recently released from Rose Medical Center in Denver after an outpatient procedure. Reportedly, the rock god is “doing well.” Reports say that Ozzy had a blood clot removed from his leg, a simple surgery that shouldn’t prevent him from cheering Kelly on as she takes to one of England’s most famous stages.
