UPDATE: Ali Lohan New Face Not From Surgery, Weight Loss Suspected 

Ali Lohan, the 17-year-old sister of Lindsay Lohan, was under public scrutiny after she made a public appearance in Beverly Hills Wednesday with a face that appeared to have underwent plastic surgery.

Ali Lohan was seen with plumper lips, a refined nose, lifted eyebrows, sculpted cheekbones and a super thin, even thinner than her usual svelte figure.

Sister Lindsay Lohan told E! news that Ali has never undergone any plastic surgery, sparking a debate on whether or not the 17-year-old went under the knife.

Other family members thought otherwise.

It's scary to see my daughter looking like this, father Michael Lohan told Radar Online. Ali was always on the thin side, but seeing how much weight she's lost there appears to be a drastic change that concerns me. This industry has a way of having a harmful effect on one's health and well-being. To see what Lindsay has gone through is one thing, I certainly hope Ali isn't going through the same thing.

Ali Lohan has just begun her career as a model, signing with Next Model Management and is the new face of PRVCY.

Will Ali Lohan be remembered for her soon-to-take-off modeling career, or for a botched plastic surgery?
