Britney Spears Sued by Former Bodyguard

A former bodyguard for Britney Spears just filed a lawsuit against her, saying he sustained physical injuries while working at her old digs at the Summit in Los Angeles.

According to the docs, Kerry Vine says Spears "negligently operated her home and business thereby causing injuries to [him]" and says the security firm he worked for forced him to perform duties that put him in harm's way.

UPDATE 7:10 PT ET Get this!!! A source involved in the situation tells us ... Vine worked at Britney's home a grand total of 3 days. On the last day he volunteered to move a small table with a few other guys. He called in sick the next day, complaining of shoulder pain.

He's been on worker's comp, we're told, ever since, and he moved the table a year ago!
