The Kardashian family are not having a good year. As Rob's legal woes over his revenge porn attack on former fiance Blac Chyna rumbles on, Kim has been hit with a potentially costly lawsuit.

According to TMZ, the reality star has been accused of ripping off a Danish makeup artist's cosmetics brand for her recently unveiled KKW Beauty line. In documents obtained by the site, Kirsten Kjaer Weis states that the 36-year-old star's use of her initials is confusing customers.

In the suit, the organic cosmetic creator describes the infringement is "knowing, willing and deliberate" and is now seeking help from the courts to block the mother-of-two from using her own 'KKW' initials, demanding profits earned since the line was unveiled on 21 June as well as undisclosed damages.

However, sources close to the Kanye West's wife tell TMZ that she went through vigorous checks and are confident there is no infringement. An insider adds that her team even "consulted several veteran trademark attorneys" before the launch.

A look at both makeup ranges and it clear that name is where the similarities end. Kardashian, who followed in the footsteps of her younger lip kit-touting sister Kylie Jenner, has gone for nude-pink plastic packaging emblazoned with the bold KKW logo and the dripping effect. A cream contour kit will set you back around $88 (£39).

Meanwhile, Weis organic products offer sleek metal packaging with a serif-font logo of the letters KW and a bronzer can cost up to $58.

Back in June, Kardashian revealed that she had sought advice from make-up artist pal Mario Dedivanovic before launching her cosmetics collection, which sold out within three hours and racked in an $14.4m on the first day.

"I think as far as feedback, my make-up artist, Mario, and I really love to bounce ideas [off each other] and we really try it out together," she told PopSugar. "And I'll ask a ton of make-up artists. I love that professional opinion, getting their ideas and feedback. I'll even FaceTime Mario like literally at 2 in the morning and show him tonnes of shades on my face. [I'll ask him] exactly which shade he likes better, just wanting to perfect the colour. If I'm on a deadline, he can be so helpful."
