Remember when you lied awake at night in high school, dreaming that just one day before the prom, Nick Lachey would come to your school with a bouquet of flowers, sing “My Everything” and ask you to the dance? No? Just me? Is that why I keep watching The Sing-Off? Anyway, none of us were quite as lucky as Corporal Kelsey DeSantis, who asked Justin Timberlake to the 236th Marine Corps Ball earlier this year… and got a “yes.”

But Timberlake’s acceptance wasn’t all for show and good PR. Dude actually made good on his promise to attend the ball with DeSantis. That’s right: DeSantis became the envy of every TRL-loving guy and gal out there and was accompanied to the Ball by Mr. “Sexyback” himself. But looks like she wasn’t the only person who considered herself lucky. After partaking in festivities, Timberlake blogged about the experience, calling it “one of the most moving evenings I’ve ever had.” Wrote the singer/actor/dancer/MySpace reviver:

“I knew I would have an evening that I wouldn’t forget… Something I could tell my friends about. What I didn’t know was how moved I would be by the whole experience.

I’ve always been very vocal about my support of our Armed Forces. I’ve always felt like they offered us the opportunity to live our lives freely without the fear that so many other nations have to endure still to this day. And, they do it without asking for anything in return. I had this very feeling walking into this dinner. So, to say I was stoked to be there would be more than accurate.”

Timberlake’s post also delved into the touching moments at the Ball. Addressing a tribute to the Marines that included footage from Pearl Harbor and 9/11, Timberlake wrote:

“It was a surreal moment to be in that room with so many of our great Marines who have such a different type of connection to those stories. One that we who don’t serve will NEVER understand. It was familial. It was like they were listening to their own blood brothers. I glanced around the room at young men and women, spouses and soldiers… At kids way beyond their years, really… All so deeply entwined. Not just by battle, even though we who have never endured anything remotely close to those experiences and have NO position to comment on… But, by having such life changing experiences through them and to not ever waver in their love and respect for our homeland. That’s what I saw. A faith in us that has been tested time and time again. And, through it all, NEVER a drop of doubt.”

The singer, of course, was thankful to his date, adorably ending his blog with the following: “Thank you Corporal Kelsey DeSantis. Thank you for inviting me. And, thank you for being my hero.” Good to see he never forgot why he was there.

Where would you like to invite Timberlake, PopWatchers? And are you jealous that she got to share the dance floor with the singer?
