Thanx to X17Online for the video...Watch the video as a crazed fan does a cartwheel onto the stage trying to rush Britney before ending her song, You Drive Me Crazy! 

Apparently the crazed man took it literally!!

Britney's dancers subdued the man until hotel security and Britney's bodyguards took over.

Britney is safe and sound and continued to finish her performance for her loyal fans!
