The former Girls Aloud singer, 28, took to Twitter yesterday (20 April) to post a picture of the newborn and to announce her name... Anaíya.
In the cute close-up black and white shot, proud mum Nadine can be seen kissing the baby's head as she holds her close to her.
Alongside the photo, Nadine wrote the simple message: "Introducing Anaíya. Xx."
It is the first time Nadine has posted a picture of her baby, or mentioned her name since announcing the birth in February.
In previous tweets, the singer has gushed about her feelings for Anaíya, her first child with fiancé Jason Bell, 36.
She admitted recently: "I haven't left her side since she was born. I tried to go out one day & broke my heart crying in the driveway. Maybe tomorrow…… Xx."
She also told a fan that the baby "looks exactly" like her mummy, that she's been living in "baby bliss" and that she cries "tears of joy at least once a day".
In a recent post, Nadine said: "I have to introduce you to my daughter soon. She is the best thing ever. Way better than sliced bread! Xx."
Nadine is the first Girls Aloud band member to have a child and announced she was expecting via Instagram in August.
When Kimberley Walsh announced she was pregnant in February, Nadine tweeted: "Congratulations Miss Kimberley. I hope you love every second as much as I did. Xx."
