Are Girls Aloud's Cheryl and Nicola Roberts reuniting for a new single?
They are, if Nicola's latest Instagram post is anything to go by.
She's shared a selfie of herself with Cheryl and producer Naughty Boy.
The photo comes after Naughty Boy revealed he is working with Cheryl on her comeback album following the birth of her son Bear last March.
Naughty Boy famously fell out with Liam's former One Direction bandmate, Zayn Malik.
