The 'Faster' hitmakers - who are made up of frontman James Dean Bradfield, bassist Nicky Wire and drummer Sean Moore - have been working on the follow-up to their 2010 album 'Postcards from a Young Man' and are particularly happy with a track, 'Four Lonely Roads', featuring the Welsh singer.
Nicky tweeted: ''The brilliant cate le bon has given us a stunning vocal on a new manics track-Four Lonely Roads-her voice is so pure+beautiful. Very excited. (sic)''
The rocker previously revealed they had been trying out different instruments to give a new element to their sound.
He tweeted last month: ''Sean been playing a french horn in the studio today-sounding wonderful xx (sic)''
The 'Design For Life' hitmakers will break their self-imposed two-year ban on performing in the UK when they headline Festival No.6 in Portmeirion in September and Nicky - who last played live with the group in Britain in December 2011 - previously revealed they will debut some new material.
He tweeted: ''M.S.P very excited about playing Festival no6 in september old stuff-rare stuff+a little bit of new stuff xx. (sic)''.
