I'm sure you may have seen this incredibly funny video, but if you haven't, here goes it. When Britney Spears' psycho fan Kyle King jumped on stage at her Mohegan Sun, Connecticut concert Brit Brit freaked! Who could blame her? She's been in the game for most of her life and having a fan try to dance with you on stage is not the norm.

Note that you don't hear Britney's screams, you just read her lips cause she lip synchs.

I'm still in shock that security allowed this to happen, but this video does make it all worth it.
