That would explain Lindsay's totally bizarre behavior the past week or so. She looks like she's down to like 75 pounds (70 without the hair). She's driving a porn producer's car and she's back at the Marmont - a clearer portent of impending doom doesn't exist. What will Lilo do without her candy (wo)man?

She's back to hanging out with her mother (also not a good sign). Blohan Sr. and Jr. were blocked from bringing little 15-year-old Ali into Club Villa last week. I'm sure Mom was bringing Lindsay into the bars by that age, but thankfully the bouncers decided against allowing history to repeat itself.

Without Sam, Lindsay is drifting like flotsam without the jetsam. She jumped up on the stage with Lilly Allen at her LA show this week - was she so wasted that she thought they were karaoke-ing in a club somewhere? Even Lilly didn't know what to make of it.

The final straw was Friday night's party at Bar Marmont, where Sam was DJ'ing a party for her designer sister, Charlotte. Her mom and funky brother Mark were there - as were dozens of celebrity friends. Even Paris Hilton was there - but not Lilo. Security was warned in advance not to let her in. Sure enough, Lindsay showed up, strung out and distraught, only to be banned from entering by five security guards. She's never been dissed like that before. Expect a meltdown of biblical proportions, any day now.
