The British make-up artist has admitted she has "always" thought of the 'Keeping Up With the Kardashians' star as a fashion and beauty muse, and designed one of her 12 lipsticks from her new Hot Lips make-up collection, called Kim K.W, after the Armenian beauty.

Speaking to PEOPLE about her latest cosmetic range, the red-headed entrepreneur said: "I always look at [Kim] and I think, 'You are a beauty icon.'"

Charlotte - who founded her eponymous skincare and beauty brand in 2013 - has revealed she modified the lip product she designed for the 42-year-old catwalk icon Kate Moss called Nude Kate to suit Kim.

Speaking about the new addition to the capsule, Charlotte said: "Kim K.W. [is a] nude [that] has a little bit of a retro pink.

"[Kim's] favourite colour before this one was Nude Kate, Kate's lip colour. [So] I was like, I want to something that ... goes back to all her beauty icons [and] that has that vintage feel.

"She loves it -- so that's been amazing."

And Charlotte's collection - which will see two dollars from each purchase made in the first two months from both Charlotte's new collection as well as her existing beauty line will be donated to Women for Women International - has sparked jealousy from her vast celebrity clientele who are yet to have a cosmetic product designed and named after them.

The mother of two - who has son Flynn Forbes with ex-husband George Forbes and daughter Valentine Waud with her spouse George Waud - explained: "The Hot Lips collection came to me because I had created a lipstick for Kate Moss, Penélope Cruz, Victoria Beckham and Sienna Miller. And [people] were like, 'Well hold on, why haven't I got a lipstick?' It happened super organically."
