On June 30, the legendary rock band The Doors announced it will sue the girls for using the band's likeness, TMZ reported. A shirt in the girl's line featured a selfie of Kendall being pasted over Jim Morrison. The shirt also features the bands' infamous logo.
The cease and desist letter from The Doors, dated on June 29, says the t-shirt line tarnishes its trademark.
Although the girls removed their vintage T-shirt line completely on June 29, including The Doors shirt, the band said it still intends to sue.
The girls have faced a huge amount of backlash this week for the shirts, particularly the ones featuring the images of deceased rappers Notorious B.I.G. and Tupac Shakur.
Biggie's mom, Voletta Wallace took to Instagram to blast the girls.
"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," she wrote. "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!!!"
As the controversy heated up, the girls quickly apologized.
"These designs were not well thought out and we deeply apologize to anyone that has been upset and/or offended, especially to the families of the artists," the sister's wrote on Twitter. "We are huge fans of their music and it was not our intention to disrespect these cultural icons in any way. The tee shirts have been pulled from retail and all images have been removed. We will use this as an opportunity to learn from these mistakes and again, we are very sorry."
Other artists featured in the line include Ozzy Osbourne, Led Zeppelin and Pink Floyd. On June 29, Ozzy's wife, Sharon Osbourne, took to Twitter to scold the reality TV stars.
"Girls, you haven't earned the right to put your face with musical icons," she wrote. "Stick to what you know…lip gloss."
