I know everyone is talking about the Sugababes reforming, but I have it for definite!

A source told me that Mutya Buena has approached Rachel Adedeji to join the reformed Sugababes.

Mutya – who was part of the original trio, which also included Keisha Buchanan and Siobhan Donaghy – has been meeting with Siobhan about a possible reunion, and thinks Rachel would be the perfect third member for the group.

An insider said: “Mutya is a huge fan of ‘The X Factor’ and couldn’t believe it when Rachel was voted out last week.

“As soon as Rachel was voted off, Mutya was on the phone seeing if it would be possible to get Rachel to join her and Siobhan in a rival Sugababes group.”

Rachel herself also fuelled rumours of joining the Sugababes when she wrote on her Twitter page on November 2nd: “I still have to keep to the x factor contract, but I do have some very exciting news man! I’ll tell you all asap! xxxxxxxxxxxxx”

Mutya left the Sugababes in 2005 to pursue a solo career, but is now keen to reunite with Siobhan to form a group to rival the new Sugababes – Heidi Range, Amelle Berrabah and Jade Ewen.
