Season fifteen of Dancing with the Stars, called Dancing with the Stars: All-Stars, premiered on September 24, 2012, on the ABC network. Season 15 was the first to feature an "all-star" cast of returning celebrities. Six of the returning finalists had already won the title in prior seasons: Kelly Monaco, Drew Lachey, Emmitt Smith, Apolo Anton Ohno, Hélio Castroneves, and Shawn Johnson. Additionally, it was the only season to date to offer fractional (0.5) scores. Five contestants reunited with their original partners, while the other eight danced with new partners.
