The original Sugababes line up have reformed and are working on new material, it has been confirmed.

According to PopJustice,  Keisha Buchanan, Mutya Buena and Siobhán Donaghy have put their differences aside and got back together to work on brand new material - possibly to be released in 2012.

The girls will not be able to call themselves Sugababes but are reportedly working with the manager who wrote some of their biggest hits as well as a number of hot new producers and songwriters including Xenomania, Emeli Sande and MNEK.

Keisha spilled the beans on Twitter earlier this week, when she Tweeted: "Hanging out in the studio with @professorgreen and two lovely ladies with bags of talent :-p lol"

It is not thought that the girls are working with Pro Green however.
