The producer, who has been working with Britney Spears, claims to be very impressed with the pop singers latest recordings, insisting the results are "magic."

J.R.Rotem, who has worked with the likes of 50 Cent, Rihanna, Lil' Kim and Paris Hilton, revealed that he was nervous meeting the former princess of pop.

However right away she tried to make him feel at ease and he's convinced that the news tracks they made together before Britney gave birth to her second son Sutton Pierce will turn out to be massive hits.

He told MTV; "I was blown away to see Britney record in the studio. You hear this finished result that sounds professional, but you don't know how much of it is overproduced, how much of it is edited.

But I found the actual talent was really there, that thing that makes people gravitate toward.

Here's this person that's arguably the biggest pop star in the world, so you would assume she could have an ego. But when I got into the studio with her, she was just a real person. She was really sweet.

She was so professional. When she gets behind the mic there's a magic that comes out, and the music that we're doing is the next level."

Rotem also believes that Britney's next album could possibly be her most diverse yet, mixing together club anthems with "slow, more introspective stuff."

Meanwhile, another one of Britney's collaborators Sean Garrett, claims her new music is pretty out there and fans will not be disappointed.

According to MTV Garrett revealed that he and Britney had been working on "some really crazy ass stuff that the world is going to love".
