The soccer superstar - who wore a number seven shirt when he played for Manchester United and England – revealed the baby’s name in a posting on his Facebook page and said both mother and baby, who was born yesterday morning (10.07.11) at Los Angeles' Cedars Sinai hospital, are “doing well”.
David – who already has three sons, Brooklyn, 12, Romeo, eight, and six-year-old Cruz, with Victoria - wrote: "I am so proud and excited to announce the birth of our daughter Harper Seven Beckham. She weighed a healthy 7lbs 10oz and arrived at 7.55 this morning, here in LA.
“Victoria is doing really well and her brothers are delighted to have a baby sister xx."
David and Victoria are thought to have chosen the name Harper – which is a popular moniker for both boys and girls in the US - because of its "lovely sound", while Seven was decided upon due because it is considered a lucky digit.
A source in Los Angeles told The Sun newspaper: "The couple loved the name Harper. It has no hidden meaning - they just fell for the name and think it has a lovely sound.
"They went for Seven as a middle name as they think it is a lucky and spiritual number. And the baby arrived around 7am in July - the seventh month."
The tot was delivered by Caesarean section, and David recently revealed the couple's house has been decorated in pink ready for their arrival.
He previously said: "It's a whole new, different thing for us. To have so much pink in the house, lilac in the house and dresses. All the clothes are ready, the room's ready. We're really excited."
