Mila Kunis, the Black Swan actress won't be attending the Marine Corps Ball with Sgt. Scott Moore in North Carolina this November. What is keeping her busy is her filming commitments.

Kunis accepted Moore's invitation to the ball after some prodding from her Friends With Benefits co-star, Justin Timberlake, on Monday. After Timberlake alerted Kunis to Moore's come-on, which he posted on YouTube, he urged, You need to do it for your country, a Reuters report said.

Kunis replied to Timberlake, I'll go. I'll do it for you. I'll do it.

An ambitious Kunis' love of career certainly outstrips her love of country.

On Access Hollywood's live show Wednesday morning, Billy Bush noted that Kunis wouldn't be able to keep the date, since she'll be busy filming two movies in November, when the Marine Corps. Ball takes place.

Kunis is slated to star as Theodora in the upcoming Sam Raimi Wizard of Oz re-imagining, Oz: The Great and Powerful, for a 2013 release. It's uncertain what the other project would be.

This hasn't prevented Cpl. Kelsey De Santis -- who is, apparently, the only female posted at the Martial Arts Center for Excellence at Marine Corps Base Quantico, in Virginia -- from issuing her own overture to Kunis' co-star Timberlake. De Santis asked Timberlake to the same ball:

De Santis might not want to hold her breath for a reply.
