Girls Aloud star Nadine Coyle has founded her own record label to release her debut solo album, Insatiable.

The 25-year-old has also signed a deal with supermarket chain Tesco, who will stock the CD exclusively when it is released on 8 November.

Dance act Faithless struck a similar deal earlier this year, and saw their album enter the chart at number two.

"The traditional model for selling an album isn't the only way of doing things," Coyle said.

"To be able to create an album where you are in complete control of your own work is a once-in-a-lifetime opportunity for an artist.'

The Northern Irish star, who won a Brit award with her Girls Aloud bandmates in2009, has been working on her solo album for nearly a year.

A , also called Insatiable, hit the internet today.

Co-written by Robbie Williams' former hitmaker Guy Chambers, it showcases a harder, guitar-led sound for the pop singer.

"I just knew we had something special when we wrote that song," said Coyle.

Two other songs heard by the 91Èȱ¬ included a more straightforward pop number, and a show-stopping minor key ballad in the style of 1970s singer-songwriters like Carole King and Joni Mitchell.

Coyle said she had sketched out most of the tracks in her London flat, before taking them to producers including William Orbit (Madonna), Toby Gad (Beyonce) and Desmond Child (Bon Jovi).

Some of the original vocals, recorded in her front room, remain on the finished record.

The supermarket deal means that Coyle's debut album, released on her Black Pen Records imprint, will be sold exclusively in 1,200 Tesco stores across the UK.

It is the chain's latest move into the music industry, having previously released CDs by Simply Red and Faithless.

Tesco also announced it would be the sole stockist of Robbie Williams' forthcoming autobiography and the launch editions of the official X Factor magazine.

Head of entertainment Rob Salter said in a statement: "We are delighted that Nadine Coyle has agreed to entrust the first album of her solo career to Tesco.

"Nadine has delivered a real album with musical integrity and, most of all, that great big warm voice and fantastic songs which we believe will speak to all of Tesco's customers."

It is understood that the star plans to release digital copies of her record through the usual outlets - including iTunes and Amazon - as well as Tesco's own download store.

Coyle's Girls Aloud bandmate Cheryl Cole is also due to release her second solo album this autumn.

The girl band are also due to return next year, having signed a deal to release three more albums with record label Fascination in 2009.

Recent tabloid stories have suggested the reunion may not happen.
