The Girls Aloud singer revealed her happy baby news on New Year's Eve by posting a photograph to Instagram showing a stork balloon emblazoned with the words 'it's a girl.'
Nadine surprised us all in August by announcing she is pregnant with her first child but had kept mum about the little one's gender until now.
In fact, on 22 December she'd tweeted: "I love how you all assume it's a girl!"
She also kept tight-lipped on who the father was for a few weeks before confirming it is former American footballer Jason Bell. They had split in 2011 but never made it public they'd got back together.
After being inundated with messages from fans thinking the baby had been born, Nadine clarified via Twitter: "Thank you for all your lovely messages. She is not born yet. That is a baby shower balloon. We can't wait until she is. Loads of love!"
She also wrote: "2013 has been the best year so far! Thank you all for your contribution. Sending loads of love, wishing you all the best for 2014!"
Back in November, she told fans she's loving every bit of her motherhood experience so far, saying: "My baby moves so much. I have motion not morning sickness. I am loving every second. Living the dream."
