Britney's Ex Pleads No Contest

Adnan Ghalib -- MEMBA HIM?!?!?! -- just pled no contest to leaving the scene of an accident after he allegedly ran over a process server back in February.

In exchange for the plea, Ghalib -- the paparazzo who dated Britney Spears at the height of her crazy days -- will have two other felony accounts against him dismissed.

Ghalib is set to be sentenced on November 20. He faces up to a year in county jail.
