Kardashian sisters Kendall and Kylie Jenner have come under fire for the designs used in their latest fashion drop.

The sisters’ new line of faux-vintage t-shirts featured various images of legendary rappers and rockers, including the Notorious B.I.G., Tupac, and Ozzy Osbourne, with the ladies own faces and K.K. initials superimposed over the original pictures. The tees were being sold for $125.

Voletta Wallace, mother of the late Biggie, took to Instagram to blast the young model-designers, calling their “exploitation” “disrespectful.” She wrote:

“I am not sure who told @kyliejenner and @kendalljenner that they had the right to do this. The disrespect of these girls to not even reach out to me or anyone connected to the estate baffles me. I have no idea why they feel they can exploit the deaths of 2pac and my Son Christopher to sell a t-shirt. This is disrespectful , disgusting, and exploitation at its worst!!!”

According to Wallace, Biggie’s estate was not contacted, and TMZ has reported that its lawyer Julian K. Petty sent a cease and desist letter to the sisters to stop selling the items in question, with a deadline of 5 p.m. tomorrow (June 30), or a lawsuit would be filed.

Petty told TMZ, “This is misappropriation at its finest. I’m curious to hear the justification. I’m even more curious to hear the proposed resolution.”

The threat worked as SPIN reports that “the rap half of ‘Rock vs. Rap’ vanished from the Kendall + Kylie website [overnight]. And around 2 p.m. Thursday, the rock tees disappeared too.”

Sharon Osbourne, wife of famed rocker Ozzy, also slammed the two women, writing:

“Girls, you haven’t earned the right to put your face with musical icons. Stick to what you know…lip gloss.”

The Doors also issued a cease and desist letter to the designers.

Jeff Jampol, manager of the Doors and the Jim Morrison estate, told Rolling Stone:

“This is a case of people who fashion themselves as celebrities who are famous for being well-known but don’t actually do anything trying to utilize and steal and capitalize on the legacies of those who actually did do something and created amazing art and messages. It’s ironic, at least, and criminal, at worst, both morally, ethically and artistically. They’re obviously attention-seeking missiles who crave celebrity and being well-known but don’t actually do anything. It’s the polar opposite of the artists that they’re trampling all over. It’s just spitting in the face and on top of art and message and soul and legacy.”

Jampol said the surviving members of the band had “zero contact” with the Jenners.

The Jenner sisters have since made a public apology, admitting that the designs were “not well thought out,” that they are “huge fans” of the artists, and that they did not mean to “disrespect these cultural icons.”
