Yesterday, Kendall and Kylie Jenner released a number of limited-edition t-shirts that featured their faces superimposed over iconic artwork from the likes of Pink Floyd, the Doors, Tupac, and Notorious B.I.G. They were properly dragged across the internet for appropriating these images, and today, as Fashionista points out, Biggie’s mother Voletta Wallace posted an Instagram expressing her outrage over the Jenners using images of her son without his estate’s permission.

“I am not sure who told @kyliejenner and @kendalljenner that they had the right to do this,” she wrote. “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!!!”

The shirts have since sold out and neither Kendall or Kylie Jenner have responded to the controversy surrounding them.
