The 17-year-old model – who is the sister of troubled actress Lindsay Lohan – has hit back at allegations she has gone under the knife, claiming her dramatically different appearance is because of a “typically teenage” flurry of growth.

Her spokesperson Steve Honig said in a statement: “Aliana has never had any type of plastic surgery in her life, nor has she ever considered it. Her success as a model lies with her natural looks and she has no interest in changing that.

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

“It’s what most people refer to as the awkward stage. Ali is growing up, that’s all."

After the teen was spotted with a noticeably different look earlier this week, Ali’s model agency have explained her new appearance is down to a “natural” change in facial features.

A spokesperson added to “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.

“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.”

“We take pastoral care of our models very seriously and encourage the models to maintain a healthy lifestyle and body shape."
