Kimberley Walsh wants her son to have a playdate with Nadine Coyle's daughter

She said: "I've not seen Nadine since Girls Aloud split, but I'd love Bobby and her baby, Anaiya, to have a play date."

Although she hasn't been in touch with Nadine - who now lives in the California - Kimberley has remained close friends with Nicola Roberts and Cheryl Fernandez-Versini and the trio are in constant contact.

She added: "I know Nicola and Cheryl inside out - we're really lucky.

"We have a group WhatsApp chat and I wake up to 50 messages from them talking about the Kardashians."

And though she doesn't see Sarah Harding - who recently split from her boyfriend Jason - very often, the pair are still in touch.

She told Closer magazine: "Sarah has had tough times but she's in a good place. She called recently and we chatted for an hour."
