Elvis' ex, Pricilla Presley, may also don a pair of blue suede shoes for the competition.

In "Dancing with the Stars," a celebrity is paired with a professional, and the duo is tasked with executing a new dance routine each week.

After each performance, judges score the dancers and the audience votes on which contestant should go home.

Last season race car driver Helio Castroneves was the fifth victor of "Dancing" along with Julianne Hough, a back-to-back winner on the show.

Other rumoured celebs that may join the series include Dutchess Fergie and Sharon Osbourne, though TMZ has said these ladies aren't likely to compete.

An air date for the return of "Dancing with the Stars" is currently unconfirmed.

UPDATE 2/17

The new season of ABC’s popular celebrity ballroom dance competition Dancing with the Stars debuts on March 17 and ABC is expected to release the names of the contestants very soon. Of course, the buzz has begun to circulate in show business circles and on the Internet that this season’s participants will be stars from the 1970s. The fueled fan speculation of the sixth edition of Dancing with the Stars has Cheryl Ladd, Priscilla Presley, Donny Osmond, Florence Henderson, Kristy McNichol, Kristi Yamaguchi, and Marla Maples rumored to samba onto the show. If the 62-year-old ex-wife of Elvis Presley joins Dancing with the Stars sixth season cast, she would be the oldest female celebrity to compete on the ABC reality series. In the 2007 fifth season of the show, actress Jane Seymour was 56-years-old when she participated.
