Liam Hemsworth, 23, was horrified by fiancée Miley Cyrus’ outrageous performance at the MTV Video Music Awards on Sunday night, according to RadarOnline.com. Miley’s provocative moves on the stage created another barrier in the on-again/off-again couple’s relationship. A source told Radar, “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.” Liam did not attend the VMAs, but it didn’t take long for Miley’s twerking to catch up to the Hunger Games star. Liam, who’s a serious actor with a starring role opposite Harrison Ford and Gary Oldman in the recently released Paranoia, believes that being with Miley is no longer an option for 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. 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.” ~ Marriska Fernandes
