Jay-Z has reportedly dropped the Sugababes from his record label.

The music mogul signed the British girl group up last year for a three-album deal but now the trio - Amelle Berrebah, Heidi Range, and Jade Ewen - have been removed from Roc-A-Fella's artist roster and company website, sparking speculation their contract has been terminated.

However, the '99 Problems' rapper is now said to be in talks with former Sugababes star Keisha Buchanan - who was replaced in the group by Jade last September and was still a member when they signed with Roc-A-Fella - and plans to launch her career in the US.

A source told The Daily Mirror newspaper: "Keisha is flying out to Los Angeles this week to record her solo album.

"Jay is serious about getting her on board. They hit it off at the BRITs afterparty in London."

Despite her good fortune, the insider insists Keisha will not be feeling pleased about how things have turned out.

The source added: "Keisha will be gutted that things have not worked out so well for the band she helped create."

Shortly after joining the group, Jade said she was excited about working with Jay-Z.

She said: "It's going to be wicked to do a collaboration with him.. I'm going to focus on this opportunity."

However, a spokesperson for the group insists they had never signed for Roc-A-Fella.
