According to director Brett Ratner, Miley Cyrus is a mini Madonna.

Miley Cyrus a mini Madonna?

"She turns it on," he told E! News this week. "A lot like Madonna."

"Where a lot of other artists are nervous or they're primping, you know, Madonna walks on and is casual; cameras are on her and then all of the sudden, wow!" Ratner said. "Same thing with Miley. She's hanging out, she's telling the jokes, she's laughing, she's signing an autograph." But then, he adds, "Camera goes on her and she was just unbelievable."

Cyrus is "a hard worker," he added. "She knows what her job is; she came and gave me 200 percent."
