Sugababes 2.0, or Mutya Keisha Siobhan (a.k.a MKS) as they are otherwise known, have announced their plans to release their first official single together on 6 September. This is the second time that the girls have moved the release date for 'Flatline,' having previously set 1 September as the ETA, before moving it to 15 September. Hopefully, this will be the last time we see the release date moved.

The publicist for the pop trio - Mutya Buena, Keisha Buchanan and Siobhan Donaghy - confirmed with Digital Spy that they have decided to move the release date for a second time so that it coincides with their appearance on Alan Carr's Chatty Man this Friday (6 Sept.) in a bid to secure more success in the charts. According to a statement released on their official website, the reformed former Sugababes have also completed work on their first album as MKS, which will be released in 2014.

"It's definitely finished, done, ready to go! We know what we want and we've got it," the girls told Digital Spy in a recent interview. "We love all the songs on the record so much that we wouldn't be willing to take anything off it if we recorded something new now...We can't mess with it again!"

Recently, the girls performed some of their new songs, including 'Boys' and 'Love Me Hard,' at a show at London's Scala, during which they also premiered their second single from the album. The girl refused to reveal which track it was that will be the single, only confirming that they have performed their second single, which will be out before 2014.
