In July, actor/singer Justin Timberlake accepted a YouTube invitation to attend a Marine Corps Ball with Cpl. Kelsey De Santis. Timberlake made good on his promise this past Saturday. But did he "bring sexy back" as well?

While looking dapper in a black tux with De Santis in tow, Timberlake attended the event in Richmond, VA and described it as "one of the most moving evenings" he's ever had.

"I felt so proud to be there," he wrote on his website. "I felt like I was getting a chance to be among my heroes." Well-played, JT. You could learn a thing or two from your 'Friends with Benefits' costar, Mila Kunis.
