Justin and Hailey Bieber have sent a cease and desist letter to a plastic surgeon after he made a TikTok video suggesting Hailey had undergone several cosmetic surgeries.
In the document, obtained by E! News, the Biebers accuse Dr Daniel Barrett of using Hailey's "name, image and likeness" to advertise his plastic surgery practice.
In his TikTok video, Barrett compares two photos of Hailey with several years between them, claiming the difference in her nose could only be a result of surgical intervention.
"Pay special attention to the nose. What do you think? Well, I'll tell you what I think. I think it's physically impossible without getting a little bit of help from someone like myself to go from this picture to that picture," Barrett says.
The cease and desist letter calls the allegation of rhinoplasty "false and uncorroborated", along with Barrett's assertion Hailey has had a skin tightening procedure, jawline contouring and filler injected into her cheeks and lips.
In addition, the Biebers take issue with Barrett's use of Justin's song 'Sorry' in the video, claiming copyright infringement.
"These flagrant and conscious infringements of our clients' rights," the letter reads, accusing Barrett of slander and defamation, among many other violations.
In a statement to E! News, Barrett doubled down, claiming he was entitled to his opinion and that the video was not made to defame the supermodel.
"The purpose of my TikTok account is to increase the transparency of plastic surgery and to educate people about plastic surgery," Barrett said.
"The purpose of the video was not to disparage Hailey Bieber in any way, the purpose of my video was to share my opinion about the procedures that I believed she may have had done based on photos alone.
"This is at the request of many of my viewers who follow me for this type of information and for my opinion."
In an Instagram comment last week, Hailey hit out at a post that compared a photo of her as a teenage to her present day look, again denying she's had any plastic surgery.
"Stop using pics that are edited by makeup artists!" she wrote.
"I've never touched my face so If you're gonna sit around and compare me at 13, and then me at 23, at least use a natural photo that wasn't edited so crazy."
