Justin Timberlake Attends Marine Corps Ball

Justin Timberlake made one of his fans very happy this weekend.

In case you forgot, De Santis -- who is stationed at the Marine Corps base at Quantico, Va. -- asked Timberlake to be her date over YouTube after another Marine asked Timberlake's "Friends With Benefits" co-star Mila Kunis to attend a Marine Corps Ball with him.

De Santis spoke to Access Hollywood Friday about her upcoming date with Timberlake, and the Marine talked about a possible dance-off with the singer.

"My friends keep saying, 'Dance-off!' They know about my skills," she said, adding, "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."

There's no word yet on on whether a dance-off took place, but it was certainly a night this Marine will never forget.
