Christopher Wallace’s mother Voletta Wallace took to Instagram Thursday to blast Kendall and Kylie Jenner for using images of her son, aka The Notorious B.I.G., and Tupac on their new line of vintage t-shirts. "The disrespect of these girls to not even reach out to me or anyone connected to the estate baffles me," she wrote on Instagram. "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!!!" Kendall and Kylie Jenner have pulled a controversial line of shirts featuring several iconic musicians after facing complaints and the threat of a lawsuit from both the Notorious B.I.G.'s estate and The Doors. Kendall apologized for the offensive shirts, which featured the sisters' faces over images of rappers including Biggie Smalls and Tupac Shakur, and album art from bands like The Doors and Pink Floyd. Kendall and Kylie were selling at least 3 of these type of shirts with Pac and Biggie at $125 a pop.
