will.i.am has hailed Britney Spears as the most disciplined artist he has ever worked with.
The Black Eyed Peas star serves as executive producer on Spears' forthcoming album Britney Jean and was surprised to discover the Toxic hitmaker's level of focus and discipline.
The Bang Bang star suspects the demands of motherhood have made Spears more professional when it comes to getting the most out of studio time, setting her apart from other artists who take a relaxed approach to the recording process.
He tells Popjustice.com, "Most artists aren't like that... Britney is the most focused and disciplined of all the artists in the industry.... Those (other artists) aren't pros. Britney's a pro. Her time is valuable: she has kids. And a lot of the time with an artist they'll go into the studio, they'll sit around, they're watching TV, they order some food, they're giggling and joking... Britney's like: "I'm coming in from 2pm until 6pm." She'll arrive at 1.30, and from 2 to 6 she'll be like BAM BAM BAM... I've never seen anything like that. Her work ethic is pretty admirable."
