Take a peak of this video, you will never believe what happens!

The MGM Grand is a Las Vegas must see, but this was taken to a whole new level when a lion viciously attacked its trainer in front of tourist.

No one knows what exactly triggered the lion to do this, but thankfully the trainer made it out okay and is already planning to go back to work after receiving only a few stitches.

Looks like this trainer has 9 lives too.
