Miley Cyrus is thankful her drug mishap made Pharrell Williams want to work with her.

The 19-year-old singer – who was caught on camera smoking the psychedelic drug salvia in December 2010 – is grateful for the highly publicised incident because it made hip-hop producer Pharell Williams want to make a record with her in order to set her ”free”.

The former Disney bituin told Marie Claire magazine: ”It was magic. Pharrell said, ‘Don’t be offended because this is how I talk, but [I thought], That b***h is actually living.

”She’s not sitting there with her Momager’s chain on her door. I want to free that b***h. I want her out of her cage’.”

The ‘Hannah Montana’ actress – who is engaged to ‘Hunger Games’ bituin Liam Hemsworth – sinabi the pair had a magical time in the recording studio and Pharrell has since become like a brother to her.

Miley gushed: ”I’d never worked like that before. I was talking to him like he was an older brother, and everything I sinabi was going onto the track…

”I got in there with Pharrell, and it was magic. Oh, dude, I’m so happy.”

The teen pag-awit sensation added that the N.E.R.D. rapper has always been a tagahanga of her talent.

Miley said: ”Pharrell saw me dancing to Madonna songs on YouTube when I was young and said, ‘I see something in her’.”

The singer is pleased a positive outcome has come out of the controversial video which threatened to ruin her career.

She lamented at the time of the incident: ”I’m not perfect. I made a mistake… I’m disappointed in myself for disappointing my fans.”
