Justin Bieber continues his transformation from squeaky clean pop sensation to utter poseur struggling for street cred. This week, the Canuck tried to hook up with a future cast member of 'Bad Girls Club,' yukked it up and toked up with buddies Lil Twist and Lil Za and possibly sipped some sizzurp.

Gee golly. He's almost as hard as Drake.

First, the random girl. It looked like Bieber and Selena Gomez were apparently done for good, and his rebound chick may have played a role in their split. Special snowflake Milyn "Mimi" Jensen reportedly had a raunchy romp with Bieber while he and Gomez were still together, though he told Jensen he was single. (If you're into that sort of thing, you perv, you can check out their hookup details in all their glorious fan fic glory courtesy of Star via Radar Online.)

Now that he actually is single, he apparently tried booty calling her again on Thursday night (Jan. 31). Unfortunately for Bieber, Jensen had already taken her talents to South Beach, heading to Miami to film for 'Bad Girls Club.' She was offered the role after selling her hookup story to a tabloid. We're sure Scooter Braun, Bieber's PR team and probably his doctors heaved a sigh of relief.

But not for long.

Not only was Bieber photographed with weed again, but now TMZ reports that other substances may have been in Biebs' presence -- and possibly his bloodstream -- at the time. Apparently there was a large bottle of codeine cough syrup — commonly known as “sizzurp” or “purple drink” (also “drank”) -- in the room with Bieber, Lil Za and Lil Twist, who were each photographed rolling blunts.

While it could technically have been innocent -- it's flu season, after all -- there were also "double cups" in the shot. For those unfamiliar, these codeine cocktails are usually served in double cups because the first cup that actually contains liquid can "sweat."

Bieber was photographed sipping from a double cup, but there's no telling for sure from the photos what was in it, because the cups were opaque. For what it's worth, Bieber's camp insists he didn't imbibe in purple drink, though violet is his favorite color, and that he's a good kid that bad influences like Lil Twist and Lil Za are leading down a bad path.

Here's hoping whatever path they choose that they don't use Bieber's Ferrari to travel it. Lil Za was pulled over for tinted windows and cited for driving without a license while behind the wheels of Bieber's whip. If you'll recall, Lil Twist was driving one of Biebs' rides when a paparazzo was struck and killed by another car -- and later did a number on the car and had the Four Seasons foot the bill.
