Turns out the Marine who asked Timberlake to the ball says he might be in for a bit of a surprises when it comes to her dancing skills.

"I honestly don't think he'll be able to keep up with my group of peopleā€¦ 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."

The Marine, who is stationed at the Marine Corps base at Quantico, won't be the only one there with a celebrity date. After Justin accepted her invitation, Sergeant Scott Moore decided to go for it and will be escorting Justin's "Friends With Benefits" co-star Mila Kunis to tonight's event.

As for any love connections that might emerge at tonight's ball? Corporal Kelsey De Santis hasn't lost hope.

"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!"
