Kensington Palace denied Kate Middleton got a Botox treatment after a U.K. plastic surgeon posted side-by-side photos of the duchess and claimed she loves a bit of baby Botox.

The palace, which rarely responds to such matters, slammed Dr. Munir Somjis claim as categorically false in a statement to the New York Post , and added: The Royal Family never endorse commercial activity. The palace declined to elaborate in response to HuffPosts questions.

Somji posted pictures on Instagram that he purported were before and after photos of the duchess. His post also promoted his practices cosmetic treatments.

Our Kate loves a bit of baby Botox, Somji wrote in the caption, suggesting the duchess was a patient. The post was removed on Thursday, but HuffPost captured a screenshot of it before it was taken down.
