Miley Cyrus and Liam Hemsworth are officially 'on a break'.

Signs Miley and Liam were going through a bad patch were apparent at the weekend, when she unfollowed him on Twitter and sparked rumours that a break or some wort of event was imminent, and now friends have confirmed they are not together at present.

A source told 'They've split for now. Miley and Liam have a very tumultuous relationship and both are exhausted. It's a complicated relationship. The wedding is on hold, for now. It's not cancelled but it doesn't look promising.'

Another friend says Miley's new image and recent behaviour - which has included her VMAs performance and appearing naked and all that licking of a hammer in her latest music video is too much for Hemsworth to handle, with the acquaintance of Liam's saying: 'Liam really does care about Miley, but her racy new look and sort of ghetto attitude isn't exactly what he signed up for. Her VMAs performance absolutely mortified him and he couldn't be more embarrassed. He doesn't really see anything sexy about what she did on stage.'

Another friend added: 'Liam is a serious actor with a growing career, whereas Miley has just turned into a joke.'

Earlier this month, it was also reported Liam was spotted 'locking lips with a random brunette' at a New York nightclub, although his representative denied this was true. A source recently said that Liam is looking for an easy way to end their relationship as he is fed up of Miley's behaviour, saying: 'They're just weeks away from calling it off permanently. Liam feels very distant emotionally from Miley these days.'
