Demi Lovato quits Twitter

Demi Lovato has deactivated her Twitter account after receiving a backlash over a joke.

The singer deactivated her account on Sunday after a joke about the Super Bowl and rapper 21 Savage - who has been arrested by ICE (Immigration and Customs Enforcement) for reportedly overstaying his visa and now faces deportation - sparked a backlash from her followers.

She tweeted during the NFL flagship game: "So far 21 savage memes have been my favourite part of the Super Bowl (sic)"

After she was criticised for her comments, Demi - who suffered a near-fatal overdose last year - then tweeted: "If you're gonna come at me for making a joke, try coming at me with some original not involving drugs."

And shortly afterwards, the 26-year-old singer declared she was done with the site.

Before deactivating her account, she wrote: "F**k Twitter. This is why I don't tweet anymore."

21 Savage was arrested in Atlanta at the weekend after ICE agents claimed he is actually a British citizen who has overstayed his United States visa for over a decade.
