Director: 'Miley Cyrus is like Madonna'

Director Brett Ratner has claimed that Miley Cyrus was as impressive as Madonna when he worked with her earlier this year.

Ratner helped to create the video for her track '7 Things', which was released from the star's Breakout album in May.

"She reminded me a lot of Madonna," he confirmed. "And I hate saying that, but what I mean is that like Madonna, she can be hanging out and laughing, and then you put the camera on her and it's like, 'Holy s***!'"

"It was the hardest video I've ever edited because every moment was great," he continued. "Every moment that she was on camera, she was amazing. She's got an incredible quality about her. Her instincts are great. She has great charisma and personality."

Speaking in June, Cyrus revealed that she is hoping to emulate the Queen of Pop by constantly changing her image over the coming years.
