Beyonce Knowles confided in Kelly Rowland about her pregnancy.

The 'Halo' singer recently announced she and husband Jay-Z were expecting their first child together but she had known about the baby news for a couple of months and was straight on the phone to her former Destiny's Child bandmate.

A source told more! magazine: "Kelly and Beyonce are so close. They talk on the phone every day and are always dishing out advice and asking each other's opinions on all areas of life, from relationships to fashion. I think Kelly was one of the very first people Bey called when she realised she was pregnant - she obviously couldn't wait to tell her."

Kelly - who is a judge on the UK version of 'The X Factor' - has revealed she knew about the pregnancy for a while and predicts Beyonce will be a great mother.

She said: "I've known about it for quite a while. Bey will be an incredible mum because she's always been motherly."

It is even thought Kelly will be godmother to the tot when he or she arrives, along with their other bandmate Michelle Williams.

The source added: "I'm 1000 per cent sure that Kelly will be a godmother - No Doubt about it. I think Beyonce's already told Kelly and their other Destiny's Child bandmate, Michelle, about their baby roles. And of course they'd be so happy to do it!"
