Cheryl Cole has congratulated Nadine Coyle on her pregnancy.
The 30-year-old singer took to Twitter to express her excitement at the news her former Girls Aloud bandmate is expecting her first child.
Cheryl wrote: "I just woke up to the news that there is to be a baby aloud!! This is so crazy. But amazing!!

Nadine, 28, is the first member of the girl group to become a mother.
Her other bandmates, Nicola Roberts, Sarah Harding and Kimberley Walsh, are yet to congratulate Nadine on her good news, but other celebrities have sent their well-wishes to the Irish beauty.

Nadine announced the biggest "craic" of her life earlier today (14.08.13) when she shared a shocked-looking picture of herself on Instragram, along with the words, "I'm having a baby. Xx".
Although she is yet to confirm the identity of the father, it is thought the secretive pop star reconciled with her ex-fiancé, former NFL player Jason Bell, earlier this year.
The sportsman - who parted ways with Nadine in June 2011 - jetted over to the UK to watch Girls Aloud perform at London's O2 arena earlier this year.
