TMZ Live: Justin Bieber's DUI Fueled by Pills & Weed ... Cops Say

TMZ Live

Justin Bieber's toxicology test results show he was high on Xanax and marijuana when Miami Beach PD pulled him over -- and now he has trouble in Canada too ... with the assault charge. With THREE live investigations ... can Bieber possibly skate on all of them?

Plus, Lindsay Lohan's in the middle of another expensive missing clothes mystery -- but the big question that stands out amongst the mayhem ... is what the hell is a two-piece mink coat?

And, a violent cat fight breaks out of Lisa Vanderpump's new show -- we talk to one of the stars of the show to see what caused it ... and how these scenes are set up on reality shows.
