Girls Aloud are back in the studio recording new material for their 10th anniversary comeback.
The No Good Advice singers - Cheryl Cole, Nadine Coyle, Sarah Harding, Nicola Roberts and Kimberley Walsh - are reforming to mark a decade in the music business, and pop producers Xenomania let slip that the band have been flexing their vocal cords.
The music makers tweeted: "Prepping to go in the studio with @NadineCoyleNOW for new GA sessions."
They added: "New GA sessions with @NicolaRoberts @KimberleyJWalsh @SarahNicHarding in the studio over the last week."
Meanwhile, LA-based Nadine is clearly excited about the comeback.
She told her Twitter followers: "Be prepared to be amazed!"
The new material is expected to be released around November, and the girls are also hoping to go on tour - despite rumours of a rift between Nadine and her bandmates.
