Mutya Keisha Siobhan plan on unleashing their debut record next year.

The pop group - who are comprised of original Sugababes trio Mutya Buena, Keisha Buchanan and Siobhan Donaghy - are currently working on their first album under the MKS name.

They have already unveiled debut single 'Flatline' and fans' appetites seem to have been whetted.

Billboard reports that MKS will release their maiden album in early 2014 via Polydor.

Keisha Buchanan added in an accompanying interview that a US album release, however, isn't scheduled so far. She said:

"There's no plans just yet, but this is the most response...that we've ever had stateside, so you never know. We're gonna push for it."

MKS meanwhile have been filming the video for single 'Flatline' out in the US.
