Kim posted a video earlier today wishing the Princess a happy birthday, and plugging her new shoe she claims to have named in honor of The Duchess.
According to Kim, the shoe's name isn't arbitrary:
"This shoe's classic quilting and graceful silhouette channels the Duchess' classic style."
Kim co-founded Shoe Dazzle, the online shoe store where the Middleton inspired shoes will be for sale.
Leave it to Kimmie to turn a royal birthday into a business event. Well played!
Check out Kim's happy birthday sales pitch for the Princess above, and a picture of the shoes below.
"The Duchess" shoe was created by Kim Kardashian and shoedazzle.co.uk to celebrate Kate Middleton's 30th birthday.
