Actress Milas Kunis believes in keeping promises.
Back in July, Sgt. Scott Moore asked the "Black Swan" star to accompany him to his Marine Corps ball, and Friday his wish was fulfilled.
Moore made the special invitation with a video that reached over 4 million viewers on Youtube. On Friday, Kunis attended the ball with him in Greenville, N.C.
Kunis has yet to make an official comment about the evening, but an enlisted Marine who attended that evening told PEOPLE that the actress "was very nice and very respectful."
After seeing the success of Moore's video, Marine Kelsey De Santis asked Kunis's "Friends With Benefits" co-star Justin Timberlake, to be her date to her Marine ball in similar fashion with a Youtube video. Timberlake recently followed suit attending the respective Marine's ball as well this month. --Natelege Whaley
