Tricky said: “She’s a professional. She loves what she does and works her butt off. Right now she’s basically doing three to four songs a day and that’s unheard of.”

Tricky – who has previously worked with Rihanna and Mariah Carey – also revealed Beyonce could team up with Jay-Z.

He added to People magazine: “It’s always a possibility. They worked together before, so it may be just a matter of getting the right record.”

Meanwhile, it has been claimed Beyonce is pregnant.

The star – who has been plagued by pregnancy rumours ever since she wed Jay-Z in a secret ceremony on April 4 – is said to be expecting her first child and was keen to tie the knot before she had the baby.

A source said: “Beyonce is 100 per cent pregnant, which is why the couple rushed their wedding.

“The wedding was thrown together so quickly because of Beyonce’s strong Christian beliefs.”
