Watch Your Mouth: Kylie Jenner Shuts Down Chris Brown After Transphobic Meme About Caitlyn -- Social Media Beef

Last week when Cailtyn Jenner revealed herself to the world, she was met with an overwhelmingly positive response. However, there are some people who had negative things to say -- including one who is close with Caitlyn's own daughter!

Yesterday, Chris Brown posted a meme to his Instagram account that praised an initiative by Akon that will bring solar power to 600 million people, and at the same time, referred to Bruce Jenner as, "that science project."

When Kylie saw the post, she took action, and left a comment saying, "Not a very nice thing to say about a friends sic dad." Brown deleted the entire post less than an hour after it went up. Kylie then made a post of her own on Twitter, saying, "State what you want about the world without bashing others. Leave a positive impact."

This tense exchange occurred just a day after Kylie was seen hugging Brown on the set of his new music video. It certainly was not the first time that he had hurt a woman that he seemed to care about.
