The producer, who has been working with Beyoncé on her upcoming album, has revealed that it is "almost done".
The 40-year-old producer and musician has been working with Beyoncé on her fifth studio album and has told fans that they won't have to wait much longer to hear her latest offering.
Speaking to Billboard.com Pharrell said: "B's album is crazy...She's very particular. She's a Virgo. And she's not going to put it out until it's ready and feels like it's right to her.
"She's got a very specific taste. I guess that's the reason she's Beyoncé. Her name is recognisable around the globe and that's huge. When you know what you want, you won't stop until you get it."
He added: "[Other people are hearing her album] and are like 'Whoa!' And she's like, 'Yeah, I'm almost done.' And she's the queen."
A new single is expected from Beyoncé before the end of the year, after the head of her record label at Columbia, suggested a possible release in December.
