The soccer star and fashion designer wife Victoria - who already have three sons, Brooklyn, 12, Romeo, eight and six-year-old Cruz together - welcomed little Harper Seven into the world on Sunday (10.07.11) and he admits having a girl is different to having boys.
In a video on his Facebook page, he said: "To have another girl in the family is really incredible. We`ve got three beautiful, healthy boys already and we`re so lucky to have that and now to have a beautiful little girl, it`s amazing.
"Having a daughter is a whole new thing. Having pink in the house and lilac in the house. And you have to be a lot more delicate with girls than with boys and I`m not used to that so it`s a whole new experience but it`s an amazing experience. To have that little bundle of joy and your hands and her making her little noises and opening her eyes - it really is an incredible moment for us."
The British athlete - who wore the number seven on the back of his shirt for many years - also spoke about the reasons behind Harper`s name.
He said: "A lot of thought goes into our children`s names and Harper was a name we`ve loved for a long time for a couple of reasons.
"One is them was because Harper is an old English name which we loved and one of the other reasons is because Victoria`s favourite book is `To Kill A Mockingbird` and the author was Harper Lee. And it`s a very strong passionate book so that`s where Harper came from.
"And Seven is partly because of the shirt number I wore for many years because I had so much luck around wearing that number and it was such an influential number throughout my career and a lucky number but that wasn`t the main reason. The reason behind Seven is that it symbolises spiritual perfection and is a lucky number around the world. We love the name. We love Harper Seven and we`re very proud of having her in our family."
