Lily Allen wasn't happy about the Tweet

Lily Allen has reported a Twitter user claiming to be an Army sniper to the Ministry Of Defence after he sent her a racist message.

The singer, 27, asked her followers for advice after she re-Tweeted the comment: 'Just seen you bought s*** I meant adopted a child from Africa #hero' yesterday.

'How do you report someone on here. That guy I retweeted should be banned,' she Tweeted.

Now the MOD has launched an investigation and the abusive profile has been shut down.

'Racism of any kind is completely unacceptable and the Army has a zero-tolerance approach to all forms of harassment and discrimination,' says an Army spokesman.

'We are aware of the alleged offensive comments and are investigating the matter. It would be inappropriate to comment further while this is on-going.'
