It was the twerk seen ‘round the world – and it was all Miley’s idea.
“Most it came from Miley’s brain,” Cyrus’s manager Larry Rudolph tells PEOPLE. “But she collaborated with [her music video director] Diane Martel, who helped her conceive it and bring in the spirit of the VMAs. And with Todd James who designed all of those amazing bears.”
Though her skimpy, flesh-colored outfit, her suggestive use of a foam finger and close contact with Thicke, 36, were panned on social media, not everyone is criticizing Cyrus’s jaw-dropping performance.
So what does Cyrus, whose new record will be released Oct 8., think about the world’s reaction? “She couldn’t have been happier about the performance,” says Rudolph.
“MTV and Miley knew exactly what they were doing,” adds a source close to Cyrus, whose team wasn’t alarmed by the performance. “No one is freaking out.”
