According to a new report, Liam was furious about Miley’s controversial performance at the recent MTV VMAs — where she was seen grinding up on Robin Thicke, even grabbing his privates — as it could jeopardize his clean-cat career path.

“Liam really does care about Miley, but her racy new look and sort of ghetto attitude isn’t exactly what he signed up for,” a source told RadarOnline.

“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.

“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.

“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.”
