STAGE TUBE: Donny Osmond's Secret 'DANCING' Rehearsal on ET!

Donny Osmond tangoed his way to the top of the scoreboard with partner Kym Johnson on "Dancing with the Stars" Monday night after receiving a 29 from the judges. Entertainment Tonight visited Osmond and Johnson as they held a top secret rehearsal for their next dance routine!

Donny was born December 9, 1957 to George and Olive Osmond in Ogden Utah. He is the seventh of nine children: eight boys and one girl. The entire Osmond Family have a long and varied career, which had a humble beginning singing barbershop harmony on Main Street Disneyland. Soon thereafter, Donny and his siblings became very successful teen idols worldwide.

Donny Osmond had performed on Broadway prior to 2006 in George M. Cohan's Little Johnny Jones, but his stay was short-lived. All that changed when Donny was invited by Disney to star in the Broadway production of Beauty and The Beast. Playing the role of the villainous Gaston was a change for Donny, who said it was an opportunity for his "mischievous side to shine." After his 12-week run ended, he was asked to return in July 2008 for the final performance as it closed its doors.

Today, Donny performs at the Las Vegas Flamingo Hotel with his sister, Marie. The show began back in September 2008 and was originally scheduled to run for 6 months. The response was so overwhelming that the Flamingo immediately asked for a two year extension. The Donny & Marie Show is scheduled to continue through October 2010.

Hosted by Tom Bergeron (America's Funniest Home Videos) and Samantha Harris (E! Entertainment), the celebrities performed choreographed dance routines which will be judged by renowned Ballroom judge Len Goodman and dancer/choreographers Bruno Tonioli andCarrie Ann Inaba.
