American producer Jim Beanz has opened up about what it's like to work with pop sensation Britney Spears and described her as "an entertainer".

Speaking to Digital Spy, Beanz explained that both singers are fantastic at what they do although there's an obvious difference between them:

"They were both very easy to work with. A lot of people would say Demi is more known as a vocalist and Britney's an entertainer, but what's most important regardless is being attentive in the studio and open to who you're working with without having an ego."

He then added that Spears was especially easy to be in the studio with when they teamed up to work on her albums 'Blackout' and 'Circus':

"Both of them were very down to earth. I worked with Britney on Blackout and Circus and she was very easy to work with. That's why the songs came out so amazing."
