Justin Timberlake attended the Marine Corps Ball Saturday in Richmond, Virginia with combat instructor Kelsey De Santis. The wife of a Marine who attended said Justin posed for pictures and seemed like a normal guy. Another attendee said Justin seemed to have a good time and it was great to see him there. De Santis invited J.T. to the ball via a YouTube video in July, saying "And if you can't go, all I can say is, 'Cry me a river!' "
