Justin Timberlake Challenged to “Dance-Off” by Marine Corps Ball Date

The gauntlet has been thrown down. Actor/Singer Justin Timberlake has been challenged to a dance-off by his date for the 2011 US Marine Corps Ball.

Corporal Kelsey De Santis, who heads to the ball in Washington later this evening (Nov. 12), has warned JT that he’d better have his moves in order before stepping on the dance floor with her.

“My friends keep saying, ‘Dance-off!’ They know about my skills,” Cpl. De Santis bragged to Access Hollywood Live. “I honestly don’t think he’ll be able to keep up with my group of people. I really don’t think he’ll be able to keep up with us.”

Kelsey added her dancing skills include “multiple signature moves,” such as “The Dougie.”

Although Justin has recently reunited with his former long-time girlfriend Jessica Biel, De Santis admitted she wouldn’t be opposed to a smooch from JT, but insists she won’t pressure the star.

“I’m single! I don’t know if a kiss will happen. I guess that’s all up to JT and what his plans are,” the Coporal gushed, adding: “I would never force anything upon him or anything like that!”

Back in July, Corporal Kelsey de Santis posted a video on YouTube.com and asked the “Cry Me a River” singer to be her date – and Timberlake accepted. Justin’s ‘Friends With Benefits’ co-star Mila Kunis is also attending the 2011 Marine Corps Ball as the date of Sergeant Scott Moore.
