Somebody on the Jersey Shore had some coke and a smile. Question is -- which cast member is a cokehead? Radaronline.com is reporting that a cocaine scandal has rocked the MTV reality show. Of course, that seems a wee bit blown out of proportion -- no pun intended. According to a Jersey Shore insider, one of the cast members spent some serious time riding the white horse while filming in South Beach. What's even more surprising is that they all weren't powdering their noses. At least substance abuse would validate their out-of-control antics. The source tells Radaronline.com that the said cast member had no problem hooking up while in the MIA. Says the source, "Miami is obviously a big drug city, and when this cast member want to score, it wasn't hard. Finding someone to buy drugs from in South Beach is as easy as asking for it. It's not hard and everyone is discreet. A connection was made and that's all it took. A lot of things were done in code. Other people knew about it but no one ratted out this person." Although Radaronline.com knows which cast member was copping the dope, they've chosen not to name names. The sources adds that the person kept the nose candy away from the other cast members. The source explains, "What do you expect from kids this age who suddenly have money? It was recreational. That's no excuse for sure. That's just the way it was." Maybe the cast member can capitalize on their dirty little secret with a trip to Celebrity Rehab once his or her 15 minutes on the Jersey Shore are up.
