Justin Timberlake Accepts Marine Corps Ball Invitation (VIDEO)

What a guy, that Justin Timberlake.

Just a few days after being asked to accompany Corporal Kelsey De Santis to the Marine Corps Ball in Washington, D.C., the 'Friends With Benefits' star accepted her long-shot invitation.

He made the big announcement during a press event with his co-star Mila Kunis, according to PEOPLE.

"I'll tell you what: I accept," Timberlake said, adding that he loved that De Santis referenced his song, 'Cry Me A River,' in her YouTube proposal.

"If my schedule works out to do it, I'd love to do it. It's an honor," he said.

Of course this whole thing started earlier this month when Sgt. Scott Moore, who is currently stationed in Afghanistan, took to YouTube to ask Kunis to go to the North Carolina Marine Corps Ball with him this fall.

Thanks to a little help from Timberlake, the actress agreed to the date before turning the tables on her co-star.

"Are you going to come?" Kunis asked Timberlake after she accepted the offer.

"They don't want me! They want you," he responded. "You need to do it for your country."

Now it looks like both Timberlake and Kunis will both be making some Marines very happy this fall.
