Following the birth of the little girl, Victoria's fellow former Spice Girls took to Twitter to congratulate the 37 year-old and her family.
Mel B, 36, who is expecting her third child later this year, wrote: 'Congrats!!! Yipeee, another spice baby is born. Damn it, wish it was me this AM cos I feel like I’m about to POP!'
Emma Bunton, 35, added: 'Big kiss to Victoria Beckham, can't wait to meet your gorgeous little girl!'
The baby girl was born at 7.55am on July 10 by elective caesarean.
