(Cover) - EN Showbiz - Ali Lohan's representatives contend that her new appearance is a result of a "growth spurt".

There has been an abundance of controversy surrounding the 17-year-old model's new look. Ali is noticeably slimmer and many speculated that she may have had plastic surgery.

Ali's representatives absolutely dismiss these assumptions, insisting that her looks are natural.

"Her success as a model lies with her natural looks and she has no interest in changing that," Ali's representative Steve Honig tells People in a formal statement.

"During the past two years, she has gone through a normal teenage growth spurt that has made her taller and slimmer."

The possibility that Ali underwent cosmetic surgery is completely out of the question, her representatives say. The thought never even crossed her mind.

"Aliana has never had any type of plastic surgery in her life, nor has she ever considered it," Steve's statement continued.

Ali is growing into her womanly body. There is nothing at all sensational about her natural maturation process.

"[Aliana's growth] has also slightly changed the composure of her face, all of which is typical of what happens to kids in their mid to late teens," Steve explained. "It's what most people refer to as the awkward stage. Ali is growing up; that's all." (C) Cover Media
