Thanks for everything you guys do," the 29-year-old wrote on Twitter after watching the video.The star also sent care packages with handwritten notes to the troops.Britney says that she feels honored to welcome the soldiers at her Femme Fatale tour and hopes that the brave service men will enjoy her show."I was so moved by the Hold It Against Me video that the Marines of HMLA-169 and VMM-266 REIN made in Afghanistan," she told American website E! Online. "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."Britney is reportedly set to perform live at the American Billboard Awards in Las Vegas this Sunday.
