Donny Osmond was declared the new champion of 'Dancing With The Stars' on Tuesday night, taking home the show's mirror ball trophy in the season finale of the ABC contest reality program. Osmond, the former teen pop star of the singing Osmond family, said the show has been a highlight in a career of ups and downs. "I did it!" Osmond exclaimed. He promptly rushed to the audience and plucked out his wife, Debbie, whom he carried across the stage. Helping push Osmond over the top was his performance Tuesday: an Argentine tango, performed with his professional dancing partner, Kym Johnson. Judge Carrie Ann Inaba hailed it as "artistry in motion." It earned the top score of the final performances Tuesday.
