Pixie Lott says her new single is one written from the heart.

The singer is due to unleash the track 'Nasty' soon as the first cut from her upcoming self-titled album.

The Brit is in a relationship with model Oliver Cheshire and she told the Metro that she drew from her life experiences for the single.

She said: "It's my first time writing from the actual experience of being in a relationship. It has really helped. I can relate to every aspect of what I'm singing, the good times and the bad times. I love writing about things that I experience, it makes songs greater."

The singer added: "It's a funky, soulful track that is very up-tempo and fresh. A few other singers had recorded it and Christina [Aguilera] was one of them so everyone wanted this song."

Lott meanwhile is due to also feature on The Vamps' upcoming single 'Wild Heart'.

She has contributed vocals to a special version of the track which is one of many different takes on the song for its single release on January 19.
