Kristin Cavallari has a coke problem

Kristin Cavallari apparently spent Super Bowl weekend scouring Miami for coke, according to Us Magazine:

But those close to the hard-partying Cavallari, 23, say that such antics have become more and more typical. “Her issues are becoming apparent to everyone,” an insider reveals. “She’s getting scary-thin and not showering regularly…She’s clearly unhealthy.”
Her Hills friends Brody Jenner, Audrina Patridge, Lo Bosworth and Stephanie Pratt have all expressed serious concerns, but to no avail. “She doesn’t think she has a problem,” a source says.
And Cavallari isn’t just a wild girl on her days off: the erratic, gaunt star has become chronically tardy to Hills tapings — when she shows up at all.
In a sad twist, her struggles may even become fodder on MTV’s hit show. “Her drug problem finally became an unavoidable conversation topic on film,” an insider says. “If MTV uses the footage, it will be clear to everyone.”

Of course the only real way to know Kristin Cavallari has a coke problem is when Lindsay Lohan jumps out of a moving vehicle to knife her in the gut. So until the dominant junkie feels her supply is threatened, it just wouldn’t feel right to pass judgment. Out loud.
