Sarah Harding is 'unsure' about recording a solo album.
The Girls Aloud singer has been working with DJ Roger Sanchez on his solo album. He revealed to Digital Spy: 'We're not sure right now. She's still in the experimenting stage at the moment.
'Whatever we come out with, we'll decide whether it's for her or me- although she will definitely feature on my album.
'It might be a good way to get the ball rolling on her project, but we haven't put any restrictions on how much or little we recod together.'
