Reformed original Sugababes Mutya Keisha Siobhan have teased more information regarding the forthcoming follow-up to September’s Flatline.

The song, whilst not officially announced as yet, is set to be a brand new track. Speaking with MSN earlier, singer Siobhan (Donaghy) said of the new release, “The only thing I can say is that the next single will be something we’ve held back, that no-one’s heard yet.”

This affirms the news the girls gave during an interview in September with Rob Copsey at Digital Spy, where Siobhan again said “It might be something that no-one has heard yet. A song we haven’t performed live before…”

The trio have just completed their sold-out ‘Sacred Three’ mini UK tour to rave reviews. Whilst we hear things may not be all as rosy as we hope in the MKS camp, we can’t wait for the release of the second single, along with new LP. Let’s just hope they have the right team around them now to ensure a stronger chart position than Flatline earned.
