Confirming their happy news, Natasha's partner and 5ive star Ritchie Neville took to Twitter earlier today (23 September) describing their baby as the "most beautiful thing he's ever seen".
He tweeted: "Daughter was born last night. Mother and baby doing great. @NatashaOfficial did the most amazing job and I have even bigger respect."
Last week (14 September), Natasha was rushed to hospital while attending Kerry Katona's wedding in suspected labour after she felt contraction pains.
After spending 48 hours in hospital, the Atomic Kitten singer was then sent home still waiting for her baby to arrive.
But today, Ritchie revealed that Natasha has finally given birth. She was four days early as she wasn't due until 26 September.

Before the arrival of their daughter, Ritchie and Natasha openly spoke of their plans to name their daughter Ella, but they are yet to officially confirm the name of their newborn.
And after opening up about many sleepless nights and Braxton Hicks throughout her pregnancy, we bet Natasha is more than pleased to finally meet her little girl.
Ritchie and Natasha began dating last year after they met while both starring on The Big Reunion. The couple announced they were expecting their first child together back in April.
Natasha is already mum to sons Josh, 11, Harry, eight and Alfie, three, from previous relationships.
