Actual stars who can actually dance.
Christopher Walken was schooled in dancing at a young age, which is probably why he's seen cutting a rug in such films as "Pennies From Heaven,""A Business Affair,""Wayne's World 2" and the 2007 remake of "Hairspray." He also famously starred in the music video for Fatboy Slim's "Weapon of Choice," where he danced for the entire duration of the song.
Kate Upton is an accomplished model, but she's also been known to showcase her dance moves on occasion. Videos of her performing the Dougie and the Cat Daddy have both gone viral on the internet.
Celebrities only pair up with professional dancers on 'DWTS,' but if they allowed celebs to pair with other celebs, we'd definitely be voting for Charlize Theron and Channing Tatum. Theron studied ballet in New York before her settling on acting, and Tatum worked shortly as an exotic dancer before starring in such dance-centric films as "Step Up" and "Magic Mike." Plus, these two looked fantastic during their dance number at this year's Oscars.
In "Grease" and "Saturday Night Fever" (and the latter's sequel, "Stayin' Alive"), John Travolta wowed with his dancing chops. He still dances every now and again, as evidenced in 1994's "Pulp Fiction" and 2007's "Hairspray" remake.
Catherine Zeta-Jones reminded us of her dance skills at the 85th Academy Awards, where she recreated a number from the 2002 film adaptation "Chicago." She also strutted her stuff in the 2012 film adaptation of "Rock of Ages."
Tom Cruise had his own extended dance sequence at the end of "Tropic Thunder"— a scene he recreated during the 2010 MTV Movie Awards. His best known moves, however, probably occured in the film "Risky Business," where he stomped around to Bob Seger in his underwear.
Again, if they allowed celeb/celeb teams on "Dancing With The Stars," Jennifer Lawrence and Bradley Cooper would be too perfect. They already got all of their fighting out of the way while training for a dance competition in "Silver Linings Playbook."
Zac Efron practically built his career on his dance-happy feet, showing off his steps in all three "High School Musical" films and the "Hairspray" remake. He also took a page out of Tom Cruise's playbook and danced in his undies in the 2012 film "The Paperboy."
Back in the early '90s, Jennifer Lopez served as a backup dancer for New Kids on the Block before landing a regular gig as a "fly girl" on the sketch comedy show "In Living Color." Nowadays, J.Lo mostly reserves her dancing for the concert stage.
He was in "Footloose."
At the age of 10, actress Zoe Saldana began concentrating on ballet at the ECOS Espacio de Danza Dance Academy in the Dominican Republic. Saldana's training helped her land her first film role as a ballet dancer in 2000's "Center Stage."
