The producer is currently working on the popstar's "crazy" new material

Pharrell Williams has said the new Beyoncé album he’s working on is almost finished.

The producer and Daft Punk collaborator says the singer’s new material is “crazy” but added that she won’t put out any music until she is absolutely happy with it.

“B’s album is crazy,” he told Billboard. “Let me tell you what it is. 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,” he continued. “I guess that’s the reason she’s Beyoncé. Her name is recognisable around the globe and that’s huge. That comes from someone that has very particular taste. When you know what you want, you won’t stop until you get it. [Other people are hearing her album] and are like ‘Whoa!’ And she’s like, ‘Yeah, I’m almost done.’ And she’s the queen.”

Back in June, R&B singer Ne-Yo, who has also worked on Beyoncé’s new material, said that fans will have to be “patient” for the album to arrive as the singer was still “trying to figure out” what they want from the album.

Beyoncé has unveiled a handful of new songs in 2013, including the track ‘Grown Woman’, which was premiered via a Pepsi advert show during the half-time show of this year’s Super Bowl, and ‘Standing On The Sun’, which she recently played in full for the first time at a gig in Belgium.
