Spears was overjoyed with the tribute, and she's now offered up tickets to her summer (11) Femme Fatale trek to the troops.

She tells E! Online, "I was so moved by the Hold It Against Me video... It warmed my heart to see our nation's soldiers enjoying themselves to my music. I am honored to have them as guests at my concert this summer. I hope they like my show as much as I loved theirs."
