Pharrell Williams has defended Miley Cyrus' transformation.

The "Get Lucky" hitmaker, who worked with the former Disney star on her new album Bangerz, has praised the 21-year-old's music and new controversial look:

"It's tough to be that age, and to have to make all those decisions yourself. And it's the people you're surrounded by, too. I'm not worried about Miley. I've seen her soul in action. I know her voice, her voice is crazy. I keep saying it to everybody: You gotta remember, she's [21] years old and enjoying her life. She's enjoying her freedom."

Miley hit the headlines after her raunchy performance with Robin Thicke at the MTV Video Music Awards but Pharrell thinks people should also focus on her talent. "When you see her, when you read her words and you listen to her musical choices, and you look at what she's wearing - I'm not talking about when she goes on stage, I'm talking about her everyday dressing - she shuts it the f**k down," the 40-year-old singer continued.

Pharrell also spoke about his own music and revealed he's working on a new solo album - his first since In My Mind released in 2006. "Something's coming up. No rapping. It's focused. That's the difference between 30 and 40. 'Cause I was 30, now I'm 40 - and I'm not rapping," he said.
