Leona Lewis has collaborated with Calvin Harris and Emeli Sande on tracks for her new album, the star has revealed.
Glassheart is due for release in March next year, but a 3-track EP, Hurt, is available this Friday (December 9).
The 'Bleeding Love' singer, who is one of only two X Factor winners to not be outsold by her runner-up since leaving the show, told the Daily Star: "I’ve worked with Calvin on a song and want to do another – he’s so talented.
"I’m planning an EP before the end of the year as I feel bad for everyone who was expecting the album this year."
She added: "But the lead song won’t be the track I’ve done with Emeli Sandé – that’s for the album."
Leona has spent much of recent weeks raising cash for the Hopefield Animal Sanctuary in Essex, and released a single, 'Collide', in September.
She is returning to the X Factor stage for the first time since 2009 this weekend.
