Ali Lohan’s shocking new look has come as a surprise to many people, but the teen’s new employer is standing behind their client.

Lindsay’s 17-year-old sister signed a contract with NEXT Model Management LA and the firm released a statement to RadarOnline.com denying that she’s had plastic surgery.

"Contrary to recent reports, I can confirm that Aliana Lohan has not had any surgery,” Alexis Borges, the agency director said. “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."

Ali Lohan has raised eyebrows with her shocking new look, and it appears she may have had some cosmetic help -- to raise her eyebrows!

A top Hollywood plastic surgeon, who has not treated the 17-year-old sister of Lindsay, says that the teen looks like she has had botox injected into her face.

Dr. Gary Alter, from E!’s now defunct TV show Dr. 90210, looked at photos of Ali and believes she’s had work done to change her appearance as she launches her modeling career.
