“She’s incredible. Like we couldn’t believe it. And when we chased it down and finally talked it was like cool. And she sings her ass off,” said Pharrell.

Pharrell then went on to rattle off the names of artists he’s been working with this year. He also revealed that he’s working a lot more with fellow The Neptunes partner Chad Hugo.

“Well the new Leah album, Leah LaBelle. New Mac Miller, Pink Slime. Chad and I have been doing a whole lot of work together,” Pharrell explained. “New Miguel, new Jay, new Usher, new Scissor Sisters. Mary song’s crazy too. Wiz Khalifa, Rick Ross.”
