Sophie Ellis Bextor has found her latest album the easiest to make.

The 'Catch You' singer, who has been working with Metronomy, Calvin Harris and Hannah Robinson on her upcoming fourth album, admitted that her career has been a rollercoaster.

She said: "This has been the easiest one by far. Definitely. And the most fun. With the least pressure. It's been a very pleasant experience. My theory is that the first album is the hardest."

Discussing her previous albums, Sophie admitted that her first album 'Read My Lips' set a benchmark for her future success.

She said: "The first album introduces you and you've got that thing of being a new person. And everybody likes new things. Then the second album you think you know what you're doing, and the record probably is more cohesive, but it tends to not do as well as the first one.

"Then for the third one, you're really aware of what you had and what's at stake. But I think if you make it through your third album you've got a career. That's the really tough bit."

Sophie has confirmed the first single from her yet-to-be-titled album will be the Freemasons collaboration 'BitterSweet'.
