Mila Kunis has been forced to change her plans to attend a military ball with a soldier fan - because she's too busy.
The Black Swan star initially accepted Sergeant Scott Moore's invitation to be his date at the Marine Corp Ball in November (11) after he made headlines last week (ends08Jul11) when he posted an open video message on YouTube.com, asking her to accompany him.
In a Fox News interview, she said, "We're gonna make this happen, sir. I'm with you."
But now the actress has had to turn down the offer because she has already committed to two films in November.
Kunis now plans to meet privately with Moore when he returns from Afghanistan, where he is currently stationed.
