The Kardashians are calling BS on a new cosmetic line with their namesake … saying they’re pissed cause it’s misleading their fans.

“Kardashian Beauty” launched over the weekend plastering the sisters’ names and faces on its website. But the sisters want to make it absolutely clear — they’re NOT part of the company in any way, shape or form.

A little backstory … back in 2012, the Kardashians teamed up with Boldface cosmetics to license and distribute color cosmetics. The sisters claim due to Boldface’s mismanagement, the partnership didn’t last long … and Boldface ultimately went belly up. Haven Beauty stepped in 2 years later but that partnership went downhill over disagreements with Haven’s owners.

That brings us to now … the Kardashians and Haven Beauty are locked in a nasty legal war and we’re told Haven Beauty’s gone rogue and forged ahead anyway, launching “Kardashian Beauty.”

A rep for the Kardashians tells TMZ the sisters vigorously reject ANY involvement with the company.

“Over the weekend, new cosmetic products were announced on the Kardashian Beauty cosmetic social media pages with pictures and statements from Kourtney, Kim and Khloe. The three Kardashian sisters are not in business with this cosmetic company.”

They go on to say, “The people selling the Kardashian Beauty brand and their predatory owners knew this and are attempting to mislead the Kardashians’ fans by stating that the Kardashians are still involved. This outrageous conduct is a legal matter and will be dealt with accordingly.”

We’ve reached out to Haven’s owners, Hillair Capital, but so far no word back.
