Britney Spears' ex BF Adnan Ghalib has been hit with a lawsuit over a hit and run.

Ram Moskowitz claims Ghalib maliciously struck him with a car, sending him flying onto the hood and then driving 30 - 40 yards before he was thrown clear -- this because Moskowitz was trying to serve Adnan with a restraining order on behalf of Britney.

It's the same incident for which Ghalib now faces 3 felony charges.

Ram suffered cuts, abrasions and a fractured wrist.

In his lawsuit filed Monday in L.A. County Superior court, Moskowitz seeks unspecified damages.
