Britney Spears was so taken with a viral video version of her song ‘Hold It Against Me’ that she gave the U.S. Marines who made it free tickets to her live show.

The singer later tweeted a picture of herself standing with the group after her show in Anaheim, California. “So honoured to meet the marines of HMLA-169 'Vipers' who made that amazing HIAM video. –Britney,” she wrote.

The video in question has already exceeded 3 million hits and featured the Marines lip-syncing to the song. Britney was so impressed by the success that she invited the group along to a date on her new hit ‘Femme Fatale’ tour.
