Glassheart is the third studio album by English singer Leona Lewis, released on 12 October 2012 by Syco Music. Glassheart was conceived in 2010 shortly after the completion of Lewis' first headline tour, The Labyrinth. Recording and production took place in Denver, Los Angeles and London; originally the album was due for release in November 2011 but was pushed back several times to accommodate new recording sessions and allow more creative time. The album was the first – and so far only – of Lewis' albums not released in North America. On Glassheart, Lewis reunites with Ryan Tedder, record producer of her previous singles "Bleeding Love" and "Happy" and songwriter Andrea Martin who co-wrote "Better in Time", in addition to a number of new collaborators such as British duo Naughty Boy and Emeli Sandé, Rodney "Darkchild" Jerkins and DJ Frank E. Producer Fraser T Smith executive produced the album after impressing Lewis with his work on Hurt: The EP, a cover song extended play that Lewis released to bridge the gap between Echo and Glassheart. "Collide", a collaboration with house music DJ Avicii, was released on 2 September 2011.
