Uh, oh. America's favorite sapphic starlet is setting off those substance abuse rumors again. Fox News is spreading reports that Linds, "isn't taking care of herself." For the repeat rehabber, that means drugs, or at least partying too much.

Lindsay and her gal-pal Sam Ronson are definitely skinny. And Sam, already not the prettiest girl at the party, works that dark-circle/heroin-pallor-look hard. Either she's spending some hard nights on the town, or she's adamantly trying to prove that superficial stuff, like concealer and blush, is beneath her notice.

We'll be able to judge Lindsay's weight loss for ourselves soon, when she appears in a red bathing suit on an episode of Living Lohan, her sister Ali's horrifying reality show. Let's hope that, if anything, she's taking the Master Cleanse a little too far, and not following the Rachel Zoe horse tranquilizer diet again.

Funny thing: Lindsay's all natural boobs are always the same size, no matter how big or small she gets...now that's a reason to gossip.
