The 32-year-old singer's boyfriend, and former 5ive member Ritchie Neville has revealed on Twitter the Atomic Kitten star gave birth to the couple's first chilld.
Daughter was born last night. Mother and baby doing great. @NatashaOfficial did the most amazing job and I have even bigger respect.— Ritchie Neville (@RitchieNeville) September 23, 2014
In further posts, Ritchie gushed the newborn is "beautiful" and also shared an inspirational quote from Nat King Cole.
Baby is the most beautiful thing I've ever seen.— Ritchie Neville (@RitchieNeville) September 23, 2014
And fatherhood,in words of Nat King Cole"I have often walked down this street before, but the pavement always stayed beneath my feet before"— Ritchie Neville (@RitchieNeville) September 23, 2014
It seems Natasha knew her baby was coming on Monday as she revealed she had been bouncing on a maternity ball - something which helps alleviate the pain of labour and bring the baby down.
Belly's gonna get ya;) this little lady weighs a ton now, the roast probably didn't help too...now back to my ball x pic.twitter.com/sWyeCpOwuw— Natasha Hamilton (@NatashaOfficial) September 21, 2014
Awake...more ball bouncing....😴😬😳— Natasha Hamilton (@NatashaOfficial) September 22, 2014
Former 'X Factor' winner Joe McElderry was one of the first of their famous friends to congratulate them on the birth.
The couple - who began dating last year after both starring in the same series of ITV2 show 'The Big Reunion' - previously revealed that they had already decided the baby would be called Ella.
Natasha was due to give birth on September 26, but had a false alarm earlier this month when she believed she was going into labour at bandmate Kerry Katona's wedding, spending the night in hospital before returning home.
On Friday, Natasha appeared eager for the arrival of the child, tweeting:
Good morning! I'm feeling giddy as I've reached my final week of pregnancy:) come on now baby, mummy, daddy & bro's so ready to meet u now x— Natasha Hamilton (@NatashaOfficial) September 19, 2014
We are glad all is well and send a bigto the happy couple!
