However, it appears this time Michelle Obama is the one that's stealing something from another famous face. Literally.
That's right. The 52-year-old first lady just revealed she uses Kate Middleton's $50 skin regimen to maintain her youthful appearance.
According to Michelle Obama's makeup artist, Carl Ray, the Duchess of Cambridge tipped the first lady off on a non-injectable 'organic Botox' called Biotulin Supreme Skin Gel.
Ray told Celebrities Style, "Michelle Obama has been using this organic Botox gel regularly on the recommendation of Kate Middleton."
Ray claims this product works wonders by smoothing out those pesky wrinkles.
Apparently, this 'organic Botox' gel contains a natural anesthetic from the Acmella oleracea plant.
This natural ingredient promises to reduce muscle contractions, which softens the facial features around the eyes and reduces fine lines and wrinkles.
Michelle's go-to gel also contains Imperata cylindrica extract, which is a grass that hails from the deserts of South America. It's known to have an intense moisturizing effect on skin.
Plus, this coveted cream has a skin-plumping Hyaluronic acid in the formula that works to keep your face looking full and youthful.
It turns out you don't have to go through an entire tube of this stuff to start seeing results, either.
Biotulin claims you can start to see visible results in as little as 60 minutes. The skin smoothing effects can last up to 24 hours.
This simple skin solution is perfect for ladies like Michelle Obama who like to keep their skincare regimen relatively low maintenance.
In fact, Ray claims the first lady typically opts for a no fuss, natural beauty routine, and keeps her skin looking fabulous with exercise, lots of water and a healthy diet.
If you're wondering what else Middleton has stashed in her beauty bag, MailOnline reports the Dutchess is also a fan of several Lancome products including Lancome Hydra Zen face cream and Lancome Advanced Genifique serum.
It just goes to show you don't always need insanely expensive face creams to look like royalty.
