Nadine Coyle is hoping to prove her vocal range on her debut solo album.
The album will be competing for chart success with her bandmate Cheryl Cole's first solo outing '3 Words', which went to Number 1 in the UK album charts.
A source told The Sun newspaper: "Guy Chambers doesn't just work with anyone. He's incredibly selective about who he agrees to collaborate with and, to be frank, he's the most expensive in the business to hire. He's seen something in Nadine he really admires."
Earlier this month, Nadine insisted there was no rivalry between her and Cheryl.
She said: "I don't see it that way at all. It's not about me versus Cheryl."
