Justin Timberlake pushed Friends With Benefits co-star Mila Kunis to accept the invitation of a Marine who asked her to a Marine Corps Ball, and now the tables have turned!

TimberlakeMarine230.jpgTimberlake told Mila, "You need to do it for your country," when Sgt. Scott Moore made a YouTube video from Afghanistan asking her to the soiree.

Now, Corporal Kelsey De Santis has posted a vid asking Timberlake to a Washington, D.C. Marine Corps gala! "I'm gonna call you out and ask you to come to the Marine Corps ball with me on Nov. 12," De Santis said. "And if you can't go, all I have to say is, cry me a river. Hit me up."

De Santis is currently the only woman serving at the Martial Arts Center for Excellence at Marine Corps Base Quantico in Virginia.

No word from Justin yet ...
