Corporal Kelsey De Santis and Justin Timberlake are headed to the Marine Corps Ball on Saturday in Washington D.C., and the star better have his dance moves ready!

“My friends keep saying, ‘Dance-off!’ They know about my skills,” Cpl. De Santis told Billy Bush and Kit Hoover and Friday’s Access Hollywood Live.

According to Kelsey, Justin – who is no slouch on the dance floor – might be in for a bit of a surprise when it comes to her talents.

“I honestly don’t think he’ll be able to keep up with my group of people… I don’t think he’ll be able to keep up with us,” she said, explaining that she has “multiple signature moves,” including “The Dougie.”

And if the night goes well with JT beside her, Kelsey said she’s open to a kiss from the superstar.

“Of course, 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,” she explained.

Adding with a laugh, “I would never force anything upon him or anything like that!”

The Marine, who is stationed at the Marine Corps base at Quantico, invited Justin to the Marine Corps Ball back in July on YouTube, saying, “And if you can’t go, all I can say is, ‘Cry me a river!’”

Kelsey asked the star to be her date after Sergeant Scott Moore posted a clip on YouTube asking Justin’s “Friends with Benefits” co-star, Mila Kunis to attend the event.
