Miley's VMA Twerking 'Last Straw' for Liam

If you were cringing during Miley Cyrus' VMA performance, well, so was her then-fiance. "Miley and Liam were already pretty much broken up at that point, but when he saw her performance and the backlash it created, it was the nail in the coffin," a source tells Radar. "That was all he needed to finally break up with Miley once and for all. He was embarrassed, disgusted, and mortified by her performance." The two officially announced their split yesterday, but E! says Liam started moving his things out of Miley's place right around the VMAs—but that source says Miley was the one to call things off, since she believed Liam was being "less than faithful to her."

Even before the breakup was announced, Hemsworth was spotted flirting with Eiza Gonzalez, a 23-year-old Mexican actress and singer, at a Las Vegas nightclub Sunday night. "They never left each other’s sides," a source tells Life & Style, and they left together around 2am. Hemsworth had also previously been linked to January Jones, but a source insists to E!, "January has nothing to do with this" even though Hemsworth was rumored to have sent her a flirty text just days ago. "January and Liam have not seen each other at all" since February, the source says. (More Miley Cyrus stories.)
