Justin Bieber is reportedly attempting to stop police leaking footage of him peeing in his prison cell, following his arrest last month.
An embarrassing video (above) has already surfaced of him getting patted down in jail after his DUI arrest in Miami Beach.
A source who has reportedly viewed the video in question told TMZ: "Justin is seen several times stumbling around while he was taking his tests. As if he had a problem with his balance ... [the video] also shows Justin taking his various tests and eventually taking a piss."
