Kate Middleton recently sparked rumors that she underwent Botox after a photo of her from June was uploaded on the official Instagram account of Kensington Palace.

The Duchess of Cambridge’s snap was shared to commemorate World Photography Day. In the picture, the mom of three is sitting outdoors with a huge smile on her face. Beside her is a young boy who is holding a camera.

Two months ago, Prince William’s wife joined children from Action for Children UK for a special photography workshop hosted by the Royal Photographic Society. Middleton serves as patron for the organization after Queen Elizabeth passed on the role to her.

But what really captured the attention of fans was how stunning the mom of three looked in the photo. Unlike her other recent outings, Middleton doesn’t seem to have wrinkles on her face. She also looks much younger in the photo considering she’s already 37.

In the past, rumors that Middleton underwent Botox also made headlines after royals uploaded side by side photos of the future Queen. One of the photos of Middleton shows her with lines on her forehead and the second photo shows that her wrinkles have cleared out.

Dr. Munir Somji from London also posted photos of Middleton on his Instagram account that has since been deleted.

“Our Kate loves a bit of baby Botox. Note the reduction of fine lines on the forehead… But also note the depression of the medial (middle part) brow but the elevation of the lateral tail of the brow,” he said.

But shortly after Somji uploaded the snaps of Prince William’s wife, a spokesperson for Kensington Palace said that his claims were categorically untrue. The source also said that the royal family doesn’t endorse commercial activity.

As such, royal fans are wondering why there are times that Middleton looks wrinkle-free, whilst other times she has fine lines on her face. And the possible reason may have to do with the use of photo editing applications.
