Leona Lewis has unveiled the video to her new single 'Lovebird'.

The clip sees the former X Factor star perform the track in a bird cage, and in front of a wind machine.

'Lovebird' is the second single to be taken from Lewis' third studio album 'Glassheart', following up October's 'Trouble', which reached number seven in the official singles charts.

It was co-written by Katy Perry and Britney Spears collaborator Bonnie McKee, Joshua Coleman and Lukasz 'Dr Luke' Gottwald, and will be released on December 9.

The star had previously confirmed 'Fireflies' to be the next track to be taken from 'Glassheart', but that release has been postponed until further confirmation.

Lewis recently denied rumours that she is dating One Direction's Liam Payne but admitted that the attention from the boyband member was "cute", saying to Look: "It's very flattering to get compliments like that. It's cute. If you have a bond with someone [age] doesn't come into it.

"I'd date someone younger or older, age doesn't matter to me. Or looks, really - it's all about maturity."

The 27-year-old also revealed that she hopes to get married before she turns 30, and that she has already picked her perfect wedding location.
