Here is video of a fan who gets on stage and tried to dance with Britney. He was pulled of stage rather quickly by the back up dancers. This tour sure has had some interesting things happen, Va ja ja's hanging out, Merry Christmas shout-outs, rumors of back up dancer hook-ups, a thing that looks like a tampon and now this. They were not kidding when labeling this tour "Circus".
Now if only they could get rid of that horrible introduction video.-Dr.FB
