Singer Demi Lovato deactivated her Twitter account following backlash over her tweets on Grammy-nominated rapper 21 Savage. The rapper, whose real name is Sha Yaa Bin Abraham-Joseph, is in custody and at risk of being deported after authorities claimed he is a UK national who has been living in the US illegally. Lovato wrote on Twitter on Sunday: “So far 21 Savage memes have been my favourite part of the Super Bowl.” People immediately began calling her out, including rapper Offset, who sort of seemed to subtweet her with the post: “All the memes and s**t ain’t funny when somebody going through some,” reports eonline.com. The 26-year-old singer tried defending and clarifying in later tweets but it wasn’t enough to calm the situation. “If you are going to come at me for making a joke, try coming at me with some original not involving drugs,” Lovato wrote. She then added: “F**k Twitter. This is why I don’t tweet any more.” (IANS)
