Liam Hemsworth unsure about future with raunchy Miley

MILEY Cyrus' controversial performance at the MTV Video Music Awards on Sunday apparently left her fiance Liam Hemsworth "mortified" and unsure about the future of their relationship.

Miley Cyrus' performance at the MTV Video Music Awards left Liam Hemsworth "mortified", according to reports.

The 'We Can't Stop' hitmaker gyrated on stage with Robin Thicke in a flesh-coloured bikini during a rendition of his single 'Blurred Lines' at the event on Sunday (25.08.13) and her fiance is said to be "embarrassed" by her antics.

A source told "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 VMA performance absolutely mortified him and he couldn't be more embarrassed. He doesn't really see anything sexy about what she did on stage."

Their relationship could be coming to an end with the 'Hunger Games' actor growing disillusioned with her wild behaviour.

The insider added: "It's pretty much over. He knows he can't stay with her when this is who she's become ... He doesn't want to babysit her anymore. He has to move on."

Liam's team are apparently pushing him to end their romance because they fear it will damage his career.

The insider added: "It's not just Liam that Miley is pushing away ... His entire team is urging him to part ways with her because she's nothing but negative for his reputation and career.

"Liam is a serious actor with a growing career, while Miley has just turned into a joke."
