Back in July, U.S. Marine Corporal Kelsey de Santis made a YouTube video asking Justin Timberlake out to the Marine Corps Ball and the singer actually said yes. On Saturday, the singer fulfilled his promise by escorting Cpl. de Santis to the event in Richmond, Virginia.

Timberlake had on a tuxedo when Cpl. de Santis met him at his hotel wearing her Marine Corps dress uniform. Once at the ball, she slipped into a low-cut silver mini.

There were plenty of photo opportunities for the star attendee, but instead of dancing and dashing, Timberlake was sweet enough to stay through the evening.
