Leona Lewis has put back the release date of her new album 'Glassheart' until 2012.

The record, which features Leona's recent hit 'Collide', was scheduled to come out in November of this year but will now be in shops early in the new year. Posting on Facebook, Leona stated that the decision was based on wanting to record more material.

"Just wanted to update everyone on the album! I'm feeling so inspired right now and have decided to continue recording! I have a collection of songs that I'm so in love with and I no there's more to be born so it means the album will come early next year." said Leona.

Leona ran into legal trouble earlier this year when Ministry of Sound producer Avicii claimed he had written 'Collide' and that the song was stolen from him. The case was settled amicably.
