Kendall and Kylie Jenner 'very sorry' for selling dead artists' T-shirts

"We will use this as an opportunity to learn from these mistakes," they said.

The shirts were going for more than $100 each and Voletta Wallace, Biggie’s mother, joined critics who slammed the use of such artists' images apparently without permission.

The two Jenner sisters took to Twitter Thursday night to announce that they had stopped selling the shirts and apologize to anyone who took offense.

"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," she wrote. "We are huge fans of their music and it was not our intention to disrespect these cultural icons in anyway. 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."

"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!!!"

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

The ad featured Jenner’s encountering a protest before handing a police officer a Pepsi to end the protest, sparking a heated debate on social media.
