Liam Hemsworth Mortified By Fiancee Miley Cyrus’ Raunchy VMA Performance: ‘He Doesn’t Want To Babysit Her Anymore,’ Says Pal

Miley Cyrus and her on-again-off-again fiancé Liam Hemsworth have had a rocky relationship, but the singer’s raunchy performance at the MTV Video Music Awards on Sunday night has put a whole new strain on their relationship and RadarOnline.com has exclusively learned the Hunger Games actor is mortified.

The 20-year-old twerked her way to controversy by grinding up on Robin Thicke — even grabbing his privates — with her tongue wagging out and an insider reveals Liam could not be going in a more clean-cut career path, which has him worried about his relationship with Miley.

“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 pal tells Radar.

“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 should be noted that Liam wasn’t even present for her VMA performance, but got an earful about it after it aired.

And as if the couple weren’t already having issues in their relationship, the insider tells Radar that Miley’s pushing Liam further and further away — even though she’s desperate to make it work with him.

“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,” the source says.

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

The insider is adamant that Miley’s wild behavior is just too much and Liam won’t take it for much longer.

“It’s pretty much over. He knows he can’t stay with her when this is who she’s become,” the source concluded.

“He doesn’t want to babysit her anymore. He has to move on.”
