Highly sought after songwriter Carla Marie Williams is penning tunes for Britney Spears' new album.

The music professional has worked with the likes of Beyonce, Kylie Minogue and Paloma Faith in the past and she is now collaborating with another pop queen.

“Recently I’ve been working with Britney, which has been great," Carla gushed to UK newspaper The Mirror.

The musician has also written a track for Beyonce's forthcoming record, which is fairly top secret at the moment.

However, Carla thinks fans will be blown away by the R&B legend's musical transformation on the next album.

“When I’m in the studio with Beyonce she makes you feel so at ease you forget she’s a superstar," she noted. “I’m loving where she’s going.

"I haven’t heard the whole album but we’re talking real issues.

"The new single we’ve done is very powerful.”

It seems Carla's other client, Britney, is moving in a similar direction to Beyonce musically speaking.

The I'm A Slave 4 U hitmaker recently revealed she is putting her all into her next LP.

"Honestly, I'm just particular with this record," Britney explained to V magazine. "It's my baby, and so I really want it done right. I would much rather have it be completely how I want it to be, whether that takes another year for me to do, or two months. I have no idea at this point. But I just know that the direction I'm going in is so good. It's the best thing I've done in a long time. I'm proud of the work, and it's very different; it's not what you would think at all. But I'm not rushing anything. I just want it to be done right, so that my fans will truly appreciate it."
