Leona Lewis published a hand-written letter to her fans explaining what happened regarding her split earlier this year from Simon Cowell's label, Syco Records.

The 'Bleeding Love' singer posted a letter onto her Instagram account to voice her feelings and the reason behind the separation, she wrote:

"It has been quite the rollercoaster year. The emotions I've felt have been more powerful, in both a positive and negative way, than anytime I've ever felt in my life.

"At some points I felt extremely depressed and other times experienced amazing highs, but it got to a place where the downs were outweighing the ups. So I'm writing this letter for anyone who has ever felt the same way."

The letter continues:

"I was terrified of walking away from a somewhat secure relationship, even though I knew that we were no longer right for each other and at times even bad for each other. However, I clung to the safety net I had grown so attached to".

It was a final creative clash that made the star realise she had no option but to leave and revealed that the label would tell everyone that she was dropped by them if she decided to leave them, she wrote:

"One day everything changed. For my fifth album, I was asked to make a record that would not have been true to myself.

"By all means as an artist in this climate, I was thankful to even get the chance to make another record. But I cannot make music that does not speak to my soul, and as scary as it seemed, I could no longer compromise myself, and so I decided to leave."

"I was threatened with the fact that if I left, it would come out that I had been dropped. That cut deep, but by this time nothing could stop me from walking away. The end of a relationship can really burn but underneath it all, there is still love there."

At the bottom of the letter, Lewis added a 'P.S.' to apologise for any spelling mistakes she may have made.
