The Duchess of Cambridge has advised Michelle Obama to use anti-wrinkle cream.
The 34-year-old royal - who has three-year-old son Prince George and eight-month-old daughter Princess Charlotte with her husband Prince William - is believed to have advised the 52-year-old First Lady of America on the best skincare products to slow down the appearance of wrinkles.
According to Michelle's make-up artist, Carl Ray, the brunette beauty - who is also known as Catherine or Kate Middleton - recommended Michelle used Biotulin Supreme Skin Gel on her face.
Speaking to Celebrities Style magazine about Michelle's beauty regime, Carl said: "Michelle Obama has been using this organic Botox gel regularly on the recommendation of Kate Middleton."
And Carl has revealed Michelle uses the serum on a "regular basis" and has found the product "unbelievable".
Carl continued: "The First Lady uses this bio Botox gel on a regular basis. The effect is unbelievable. One of the constituents of this gel is Spilanthol, a biological local anesthetic extracted from the plant Acmella Oleracea (paracress). Biotulin, as this gel is called, smooths out wrinkles within just one hour."
Meanwhile, Catherine and Michelle have both been credited as the most inspirational women girls aged between six to 12 years old look up to in a study undertaken by Disney UK.
Whilst Catherine was pitted highly in the study after receiving eight per cent of the vote, her mother-in-law, Queen Elizabeth, only just scraped into the Top 10 and was ranked ninth place after actress Emma Watson, Angelina Jolie, TV presenter Holly Willoughby and author J.K. Rowling.
