Lindsay Lohan’s kid sister, Ali Lohan, makes her modeling debut on the cover of Fault magazine, and definitely looks the part, wearing edgy outfits, heavy makeup and a short bob hairdo.

Ali, who is 17, first appeared in the public eye as a whispy teen and seemingly matured over night, although she was only 15 at the time.

She dropped out of the spotlight for awhile and then re-emerged, raising eyebrows because of her thin, model-like frame. She’s now also listed as 5’8″ tall.

She signed a modeling contract with NEXT Model Management in August and landed her first gig with Fault’s winter 2011 issue, which goes on sale next month.

The black-and-white shoot features Lohan in a racy sleeveless rubber tube dress, and a long white sweater.

There were rumors that Ali had plastic surgery because her weight loss, and an apparent growth spurt gave her a more angular face.

One plastic surgeon was quoted claiming Ali had botox and fillers.

But the Lohan clan denies it and Lindsay has ripped her sister’s “haters” on Twitter.

“I love how haters pick on my sister yet every runway model is just as thin! My sister is gorgeous and I’m so proud of her and her career!!!!” she wrote.

Alexis Bores, NEXT agency director told E! News, “I can confirm that Aliana Lohan has not had any surgery.”

“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,” he added.

“Aliana is a beautiful 17-year-old girl who is growing into her face and body, as is the norm for someone of her age,” he said.
