Kim Kardashian told off her devoted fans for making her "stressed" out after they criticised her swatching technique.

The reality star recently shared a series of pictures of her arm covered in swatches of products from her KKW Beauty range on Snapchat and she was criticised by fans and beauty blogger Jeffree Star for not being able to swatch properly, and she later told them their comments have been stressing her out.

"I didn’t know how to... swatch powders at the beginning - I’m learning," she said. "You’re stressing me... out... OK, I'm learning how to swatch. At least, the product, at least, we can back it up. Just wait til you get it, you'll be pleasantly surprised."

She said she's not worried before pointing to a pimple on her chin and sarcastically saying, "Thank you".

Kim also filmed herself having a tutorial about how to apply cosmetics to her arm properly from a make-up artist in her dressing room.

Some of Kim's fans took aim at Jeffree and began trolling him for tweeting that her swatches "look like chalk", so Kim took to Snapchat again to ask them to leave him alone while she was being given make-up to her cleavage while dressed in a nude figure-hugging bodysuit.

"I see that my fans are totally hating on someone like Jeffree Starr for being honest about my struggle swatches but because of his remarks, I'm learning from the best, from Mario, how to swatch properly," she said.

"I welcome honest comments about my products and because of it, I'm swatching better now. So everyone, get off his a*s, and let's not be so negative, we're all in this together, there's room for all of us. Love you Jeffree."

Jeffree replied, tweeting, "The fact that someone like @KimKardashian can understand and take real feedback is what a REAL boss... does. Love you."

Kim later posted a series of Snapchats showing her in a sparkly Gucci bodysuit, including a close-up shot of her bottom in the revealing outfit.
