Britney JUST dropped her brand-new video, "3," and it's like she went to the sexy Olympics and took home the gold medal. Thanks, Brit, for skipping the sexy-cute dress-up antics of your  "If U Seek Amy" and "Womanizer" videos and going back to your dance roots in your hottest video since "I'm A Slave 4 U."

Watch Britney's "3" video, directed by Diane Martel, now.
