Remember this summer when Justin Timberlake was invited to the Marine Corps ball via Youtube? Cpl. Kelsey DeSantis sent out the invite to Justin and he actually accepted! Justin seemed to have a great time at the ball, "Thank you Corporal Kelsey DeSantis. Thank you for inviting me. And, thank you for being my hero," he wrote on his website. We think that was really sweet of Justin and so unlike most of the celebrities in Hollywood, and this is reason number 160032 why we love Justin Timberlake! Check out the invitation that Kelsey sent Justin below! (wtvr)
