Nicola Roberts hasn't ruled out doing another solo album.
The former Girls Aloud star has been busy helping other artists whilst on hiatus, but admitted she feels a "release of creativity" in the studio and when that urge becomes "intolerable" she's vowed to switch to writing her own music.
Asked if she'll do another solo project, she said: "I'm definitely not saying never. And it's interesting because there's always only so much creativity you can give to another artist's session because there will always be a brief for that session. You can be in a session where the artist would say to you - 'oh, I wouldn't really say that myself'. Then it stunts your own release of creativity.
"So there is definitely a big portion of me that needs to create and so when that starts to become intolerable then I would have to let that out. When I feel that I no longer want to confine myself to these lines of making a song anymore and when I want to express myself in a particular way then that is when it will become a need."
Meanwhile, Nicola - who has one solo album 'Cinderella Eyes' - said she's thankful for having time off to "grow" and move on from the "bubble" that is Girls Aloud.
She told website The 405: "For the past two years all that I've been doing is writing. And it was really just coming out of the Girls Aloud 10th birthday celebration thing and the tour and never really stopping for a second. Like, I went from Girls Aloud to my own record then back to Girls Aloud and it was just... I have needed a few years to just grow, I think, and come out of the bubble."
