Apple co-founder Steve Wozniak is among 13 celebrities who will compete on the ABC series' eighth season that begins March 9, the network said Sunday.
Romantic relationships may be put to the test this time around, with couples taking to the dance floor with and against each other.
Pop star Jewel and her husband, rodeo champion Ty Murray, will compete for bragging rights, ABC said, while country singer Chuck Wicks will take the floor with his girlfriend, two-time "Dancing with the Stars" champion Julianne Hough.
Last November, Hough had said she planned to focus on her newly launched country music career and didn't plan to return to the show.
Professional dancers and series regulars Maksim Chmerkovskiy and Karina Smirnoff, who are newly engaged, will be waltzing in the arms of others.
Olympic gold-medal gymnast Shawn Johnson gets to make her mark just by showing up: At 17, she's the youngest competitor to date, ABC said.
Another star athlete in the field is Lawrence Taylor, the former New York Giant and NFL Hall of Famer.
The other celebrity hoofers are Go-Go's lead singer Belinda Carlisle; rapper Lil' Kim; actress Denise Richards; actor-comedian David Alan Grier (Comedy Central's "Chocolate News"); Gilles Marini, who played the neighbor ogled by Kim Cattrall's Samantha in the "Sex and the City" film; Steve-O (MTV's "Wildboyz") and TV host Nancy O'Dell of "Access Hollywood."
"Dancing with the Stars" is hosted by Tom Bergeron and Samantha Harris, with Len Goodman, Bruno Tonioli and Carrie Ann Inaba judging the contestants.
