Island Records has stating categorically that Sugababes member Amelle Berrabah is not leaving the pop trio.

The Sun newspaper today reported that secret auditions were held at the weekend for a new singer. However, an official statement has denied there are any plans to replace Berrabah, who joined the group 18 months ago following the departure of Mutya Buena. Buena is currently pursuing a solo career.

"Contrary to speculation Amelle Berrabah is not leaving Sugababes," said an Island Records statement.

"Amelle and her bandmates Keisha Buchanan and Heidi Range are in rehearsals this week for forthcoming live shows and have just completed filming for the video for their new single "About You Now" which will be released on Sept. 24, upfront of their new studio album "Change" which is released on Oct. 8."

The statement added that there have been "no auditions for a new band member."

"Things couldn't be better in the band at the moment," said Keisha Buchanan in a statement. "Amelle, Heidi and I are a rock solid team".

The group has denied the claims by The Sun that Berrabah's bandmates were unhappy with her level of commitment.

"I'm 110% committed to Sugababes," said Berrabah. "It's a dream come true. I can't wait to perform the new album live".

Sugababes has scored four U.K. No. 1 singles and a joint No. 1 with Girls Aloud on the Comic Relief charity single "Walk This Way" in March 2007.
