Amanda Bynes is showing no sign of letting up on her feud with half of Hollywood, this time putting Miley Cyrus in her sights.

The volatile former teen star took to Twitter yesterday to deliver a short, but succinct, message, accompanied by a picture, just in case her followers didn't realise who she was talking about...

Cyrus's fans have been quick to jump to her defence, which probably won't trouble Bynes anyway. She's been warming up in recent weeks, most controversially with her attack on Rihanna, when she allegedly decided "Chris Brown beat you because you're not pretty enough".

Bynes' Twitter account has been burning with vitriol recently

Ms Bynes later complained that her Twitter account had been hacked, because she has so many followers, so watch this space to see if the same explanation is forthcoming, something to quieten the Miley fans at least.
