Twigs, real name Tahliah Debrett Barnett, is who reportedly engaged to Hollywood star Robert Pattinson, told Britain's Sunday Times Magazine about the robbery, but refused to go into detail, saying, "I was mugged outside the yoga studio."

She also told the publication that she recently broke down over racist comments from online trolls after she replied to a fan on whose friend was dying of cancer.

The fan tweeted a picture of himself with his ill friend in hospital, and revealed the young woman listened to Twigs' music to cheer herself up. However, the singer was stunned when they were subsequently bombarded with nasty comments.

She says, "They all started attacking her. Within 20 seconds it was just like n**ga, monkey, ugly, die b**ch, all this stuff on his feed. It broke my heart... this lady who is really sick and is probably going to die... Sometimes people are going to treat you differently because of the colour of your skin. Sometimes you're going to have to work 10 times harder than somebody else to get the same appreciation, but never use it as an excuse."
