Donny Osmond, 51, and professional dancing partner Kym Johnson won the Season Nine trophy – a mirror ball – on ABC's Dancing With the Stars Tuesday night. The judges, including Carrie Ann Inaba, left, helped Donny beat singer Mya and third-place finisher Kelly Osbourne. The broadwcast was not without excitement – a fireworks show on stage set a tarp aflame. Two workers quickly extinguished the fire and no one was injured. (Photo: WENN)
