Leona Lewis has described 'Glassheart' as the best album she has ever made.

The 2006 X-Factor winner, who releases her third studio effort later this month, told The Sun that she couldn’t be more happy with the way the record turned out:

"It totally represents me and I love it. It's almost six years since my first album so I have progressed a bit more. I also got the chance to try new things which was really fun.

"I think it's really important with the third album to make it as good as you can. I think it's the best album I've ever made.”

The 27-year-old, who releases new single, 'Trouble,' today, also claimed that label boss Simon Cowell is just as pleased with the follow-up to 2009’s 'Echo':

"Simon has heard the album and is really supportive about it. He's into it and helped me pick the tracks. He's very involved in that way.

"I've taken a bit of time on it as I really wanted to be able to focus on it and have the exact right tracks that I wanted."
