The latest Lohan to fall into a downward spiral is Lindsay's little sis Ali (or, ahem, Aliana), who recently signed a modeling contract, and this week she was photographed with a new look that sorta screams "plastic surgery." Not only that, the Long Island teen is allegedly down to just 95 lbs, and a Columbia University professor says she "has the look of someone who may binge and purge plus calorie restrict."

Doctors told Radar that it looks like she had botox injected into her face, but her modeling rep says it's totally natural for a girl's face to change like that! No really, that's actually what she said: "As a young girl who is growing up, it's natural for her facial features to change slightly, and we see this with many of the younger models we represent." (Sadly, that last part is probably true.) But the experts say Ali "is very underweight. By looking at her cheekbones you can tell she has muscle wasting going on."

While Lindsay says her sister has never gone under the knife, their father Michael is alarmed, saying, “It’s scary to see my daughter looking like this." Someone give these kids their Carvel black card back.
