In past seasons, the move from the gridiron to the dance floor has been smooth — and that may give Lawrence Taylor the upper hand in the competition.
The football Hall-of-Famer was the New York Giants' first-round draft pick in 1981 and became the league's defensive player of the year in his first season.
In addition, his speed, intensity and strength helped make him one of the most memorable linebackers the NFL has ever seen.
Taylor had the second highest number of all time for career sacks when he retired in 1993. Let's see if that fancy footwork translates into ballroom supremacy.
Singer Jewel rocketed to superstardom in 1995 when she released her debut album, "Pieces of You." Her inspired vocals and soft rhythms proved too much for fans to resist, on singles like "Who Will Save Your Soul," "Foolish Games and "You Were Meant for Me."
The songwriter parlayed her success into six more solo records, books of poems and film and television work.
Jewel has served as a guest judge on "American Idol" and hosted "Nashville Star."
In 2007, the pop songstress tried a new genre — country music. Her duet with Jason Michael Carroll, "No Good in Goodbye," was just the beginning.
In 2008, she released her own full country album, "Perfectly Clear," which debuted at No. 1 on Billboard's country music chart.
Jewel loves country music so much, she roped in her own cowboy. She married rodeo champion Ty Murray in August 2008, and the couple has the distinction of becoming the first married pair to compete in the same season of "DWS."
Belinda Carlisle fronted one of the most successful girl groups of the 1980s. With hits like "Our Lips Are Sealed" and "We Got the Beat," Carlisle and the Go-Gos dominated 80s airwaves.
Following the band's 1985 breakup, Carlisle went on to a very successful solo career, which included hits like "Mad About You," "I Get Weak" and "Heaven Is a Place on Earth."
The pop icon shared her rock-star know-how with famous offspring seeking the spotlight for their own right on MTV's "Rock the Cradle." The singer also has become a spokeswoman for NutriSystem.
In past seasons, contestants have danced away the pounds. Will Carlisle be able to do the same and take home the trophy?
Actress and model Denise Richards has a face that was etched into pop culture's minds in the 1990s, when the sultry thespian melted the silver screen with roles in "Wild Things" and the James Bond flick "The World Is Not Enough."
Men's magazines often have place Richards among the most beautiful women in the world.
Recently, the mother of two has become a tabloid favorite, with readers intrigued by every facet of her personal life. Her reality show, "Denise Richards: It's Complicated," let fans see her life with her father and daughters, Sam and Lola.
Surely Richards will bring her sexy brand of style to "DWS" -- but will it be enough to secure judges' and viewers' votes?
At just 17 years old, Shawn Johnson is the youngest competitor ever on "DWS." But age won't be a factor for the Olympic gymnast, who already proved to the world she was a top-tier, world-class competitor when she brought home a gold and silver medal in the Summer 2008 Olympic games.
