Kendall and Kylie Jenner have landed themselves in hot water.

The sisters have had to remove a line of t-shirts from their clothing range bearing images of a number of artists including The Doors, Pink Floyd, Ozzy Osbourne, and the late Tupac Shakur and Notorious BIG. They withdrew the items after backlash from family members of a number of the artists. Notorious BIG's mother Voletta Wallace criticised the reality stars on Instagram, claiming they were exploiting his death and the death of Tupac. She also said that neither the family nor the estate of Notorious BIG were contacted about using his likeness. https://www.instagram.com/p/BV7idXEAt5_/ Julian K Petty, a lawyer for the artist's estate, sent a cease-and-desist letter yesterday, threatening to pursue legal if the t-shirts continued to be sold, reports the Guardian. "This is misappropriation at its finest,” he said. “I’m curious to hear the justification. I’m even more curious to hear the proposed resolution." Sharon Osbourne, ex-wife of Ozzy Osbourne, also weighed in on Twitter. https://twitter.com/MrsSOsbourne/status/880503475485855744 The sisters have since released a statement on their Twitter accounts, apologising for the collection. "These designs were not well thought out and we deeply apologise to anyone that has been upset and/or offended, especially to the families of the artists," the statement reads. https://twitter.com/KendallJenner/status/880527206362914816 The 'vintage' t-shirts were part of the girls' Kendall + Kylie collection and were priced at $125 each.
