Nicola Roberts is said to be writing material for Cheryl Cole's upcoming album.
According to the Daily Mirror, the Girls Aloud pals will collaborate on Cheryl's album which is due for release next year and Nicola has already honed her writing skills on Little Mix's album DNA.
Cheryl has been keen to get best mate Nicola to write for her for a while, but she's been too busy working in the worlds of make-up and fashion so far.
In 2012, Cheryl said of her album A Million Lights: "I was trying to get [Nicola] to write [a song] but she didn't have time. Cheers for that, too busy creating lipstick colours!"
The pair and bandmate Kimberley Walsh have always been the closest members of Girls Aloud, which Kimberley admitted in her recent autobiography A Whole Lot Of History.
She wrote: "I think we'd have been friends even if we weren't in a band together. But I'm not sure that would have been the case for me with Nadine or even Sarah. That's not to say I don't care about them or respect them. They're just very different from me and I don't always understand where they're coming from.
"I suppose you choose the people you want to spend time with because they're the people you get on with and who bring out the best in you."
