The 17-year-old signed a multi-year modeling contract with NEXT Model Management in August, and aside from modeling for Lindsay's 6126 spring/summer 2011 collection, the art and fashion magazine cover is Ali's first big booking.
In the photo spread, Lindsay's lil' sis sports a series of high fashion looks, including a a leather bustier dress and a chunky fur sweater -- which she wears without pants. Ali also wears a dramatic black bob wig and thick eyebrows in the edgy pictorial.
Ali came under fire in September when it was believed she underwent plastic surgery; her rep was quick to dismiss the rumors.
"Aliana has never had any type of plastic surgery in her life, nor has she ever considered it," her rep told Us Weekly. "Her success as a model lies with her natural looks and she has no interest in changing that."
