'X Factor' Kitty Brucknell covers David Guetta's 'Titanium' - video
The singer has teamed up with her former fellow X Factor contestant Bradley Johnson (from boyband NuVibe) to perform a rendition of 'Titanium'.
The star uploaded a clip of the stripped-down version to her YouTube channel, while working on material for her debut album.
"So I've been in the studio a lot this week...and who did I bump into, but the gorgeous Bradley from last year's show (he was in NuVibe but now he is working on his solo album)," Brucknell wrote.
"So, we decided to have a little fun in a break, and came up with this! And yes, that IS me on the piano!"
She added: "We recorded it in one take, then filmed it - we had so much fun doing this, so please share with all your friends and follow us on twitter/facebook. New music coming soon, but I thought you'd love this!"
Brucknell recently told Digital Spy that her new music is "quite dark lyrically" and that she wants "to create headlines about what [she's] singing".
