The reason Lindsay Lohan bailed on her Today Show interview at the last minute yesterday was because she’d just found out she’d tested positive for alcohol — meaning she has to appear in court today for another probation violation hearing — and a “I’m serious about my sobriety” interview would have probably seemed a little hollow, given the circumstances. (Good thing she already gave that interview to Life & Style earlier this week, then. Nothing says “humbled by past mistakes” and “well-grounded” like sitting in front of a eight foot high portrait of yourself.) TMZ says:

Lindsay was tested twice last week — [she] tested positive for alcohol on one of the tests and negative on the other. One of the tests was administered just after Lindsay had a rooftop barbecue party.

Sources [say] the L.A. County Probation Department will ask [the judge] to yank her out of house arrest and throw her in L.A. County Jail.

The Probation Department is pissed off because they tried to force Lindsay to take two tests in May but Lindsay’s lawyer refused to make Lindsay submit, claiming it wasn’t part of her probation. Turns out it was, so Lindsay subsequently took the two tests… one of which she failed.

There’s stupid, and then there’s Lindsay Lohan. Unbelievable. Even Ryan Dunn makes better life decisions than that bitch does.
