Mutya Keisha Siobhan's new album is their ''strongest yet''.

The girl band - who were the original line-up of the Sugababes - have finished their first album together since 2000's 'One Touch' and believe their comeback record is more representative of them then their past manufactured hits.

Keisha Buchanan told the Daily Star on Sunday newspaper: ''The album is finished and we all love it. I think it's the strongest yet. It's not manufactured in any way.

''We turned down big songs that would be huge hits because they weren't right for the album. We haven't been afraid to make the music we wanted to make.''

The 'Overload' singers have been faced with an ever-changing line-up since Siobhan Donaghy left the Sugababes in 2001, followed by Mutya Buena in 2005 and Keisha in 2009, but despite only having made one album together, the girl band's longest-serving member Keisha thinks the original members were the best vocally.

Keisha said: ''I'm not going to stand here and slag anyone off. I had a great time with all the girls and am proud of all the albums I've made, but I do feel this line-up is the strongest vocally. Our voices blend so well together.''

MKS have teamed up with the likes of Emeli Sandé, Sia and Sugababes producer Cameron McVey on their new album.
