Commenting on the racist remarks on Twitter about her rumoured relationship with actor Robert Pattinson, singer FKA Twigs says she is shocked and disgusted.

The singer, whose real name is Tahliah Debrett Barnett, ranted at the social networking website Twitter Sunday, reports dailymail.co.uk.

`I am genuinely shocked and disgusted at the amount of racism that has been infecting my account the past week,` she tweeted.
