Pop singer Camila Cabello is apologizing for racist comments and memes she posted on her Tumblr when she was a teenager. In a tweeted statement, the “Havana” warbler says that when she was younger, “I used language that I am deeply ashamed of and will regret forever.” She said she was “uneducated and ignorant” when she made the 2012 posts but has since grown up. “Once you know better, you do better, and that’s all I can do,” she said.
