Beyonce has the ability to "make you forget she's a superstar", according to songwriter Carla Marie Williams.

The music professional has been working with the R&B legend on her upcoming album. She has written a track for the record, which is top secret, but promised fans they will be blown away by Beyonce's musical transformation on her next offering.

“When I’m in the studio with Beyonce she makes you feel so at ease you forget she’s a superstar," she told British newspaper The Mirror. “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.”

Carla has previously worked with the likes of 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 added.

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."
