Mutya Keisha Siobhan have been forced into denying speculation that they have fallen out with each other.

Suggestion emerged recently about the future of the original Sugababes trio when Keisha Buchanan was seen on Twitter angrily trying to get into contact with a seemingly AWOL Mutya Buena.

She wrote: "Hello???????!!!!!!!!!!!!!!!!! Clearly I have to start tweeting you."

Buchanan continued her quest for Buena on Instagram, but the two singers later tweeted that the latter had been on holiday with her phone on silent.

A rep for the group, who have released one single so far, told the Mirror that all is well within their camp:

"There’s nothing going on here. The band will be releasing their second single and their album later this year."

MKS also denied in December that they had been dropped by their record label Polydor.
