Leona Lewis has spoken out this week about the real reason that she left Simon Cowell’s record label Syco. The popular singer told Newsbeat that she left in order to save her career, saying that things became more and more ‘complicated’ as Syco grew. The X Factor winner, who enjoyed a long spell at number one in 2007 with her debut single Bleeding Love, revealed that things weren’t ‘so great’. Leona at the Glamour awards in London. “It was amazing at first because it was very intimate and there wasn’t a lot of people working for it,” she stated. “Then it grew and grew which is great for them, but for me it wasn’t so great,” she continued, adding that she had released three albums with the label who also manage One Direction, Olly Murs and Labrinth. “A lot of decisions had to be made by a lot of different people. “Of course Simon being involved – there was a lot of decisions that had to go through him."

Leona, who is now signed with Island Records alongside Florence and The Machine, is releasing a new single Fire Under My Feet this week. “The song is all about overcoming adversity and obstacles that might be in your way." She is releasing a new album this year. “I wanted it to be about real people and real stories. People that you wouldn’t necessarily think might go the distance and they do. “I’ve had to build myself up quite a bit. I feel like I have come out of a situation where I felt a bit down. “There’s no bad blood at all,” she added. “He [Simon] sent me a really lovely note the other week saying they miss me at the label." Leona has stated there's no 'bad blood' between them. “There’s nothing but love there. He knew I had to leave. He was upset about it but it was time for something new so I’m excited about moving on and doing something different.”
