whata f***

That's what some of our Marines have been doing in the Middle East. We've already seen troops lip-syncing and dancing to Lady Gaga and Miley Cyrus, but now it's time for Britney Spears. You gotta check out the new video for "Hold It Against Me" that's coming to us via YouTube from "somewhere deep in the heart of Afghanistan."

"I am in LOVE with this..." Brit-Brit tweeted in response to the clip. "I always knew our soldiers were fierce! Thanks for everything you guys do."

God Bless our troops...and Britney Spears.
