Mutya's Number Change Angered Sugababes

Former Sugababes member Mutya Buena insisted she left the group with no ill feelings but now, rumors fly that that may not be the solid truth when she had recently changed her number without informing the current members.

Buena, together with childhood friend Keisha Buchanan, had founded the girl group in 1998 when they were just 13. Their debut single "Overload" had been a massive hit and made the group popular when it made the UK Top 10. Buena left the group in December 2005, which fuelled earlier reports that the girls were not in accordance with each other. They constantly deny the rumors.

But now, Buchanan has allegedly said their friendship fell out when the "This Is Not Love" singer didn't inform them of her new phone number.

"We were (on speaking terms), but then she changed her number. I saw her at the MOBOs (Music of Black Origin Awarsd) and she was like, 'No, I have no problem with you and Heidi,'" Buchanan says.

"I don't know exactly what's going on, but obviously things have been said. I'm sure someone's not sitting there making it up," she continues.
