Singer responds to online comments about fiancé

Katy Perry has blasted a fan for writing negative posts about Russell Brand on Twitter.

The user has been urging the singer to dump her fiancé, 34.

‘I know [Russell] is wrong for you,’ the fan wrote to Katy.

‘He’s awful, ugly, sick and disgusting! You have to leave him before it’s too late. I love you so much and know it’s wrong for you to be with him!’

But now Katy, 24, has defended her man.

‘Hey can you please stop being so disrespectful?’ she wrote. ‘It’s not cool, I would really appreciate it.’

Katy and Russell got engaged in India on New Year’s Eve.
