British football superstar David Beckham's and his wife Victoria have named their new baby daughter Harper Seven.

She is their first daughter after three sons.

Harper Seven was born yesterday at Cedars Sinai hospital in Los Angeles.

"I am so proud and excited to announce the birth of our daughter Harper Seven Beckham," wrote the footballer on his Facebook page.

"She weighed a healthy 7lbs 10oz (3.5 kilograms) 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."

The Beckhams' three sons also have unusual names --- Brooklyn, 12, Romeo, eight, and Cruz, six.

The spokesman dismissed as "rubbish" a report in one British newspaper that Prince William could be godfather for the latest addition to the Beckham family.

The footballer was spotted talking to Britain's future king at a reception on Friday evening at the residence of Britain's consul-general in LA, where the royal couple stayed over the weekend.

Former England captain David, 36, and pop star-turned fashion designer Victoria, 37, married in 1999 and live in Los Angeles where he plays for LA Galaxy.

Victoria -- known as "Posh Spice" during her days with the Spice Girls -- had said before her pregnancy was announced that she was open to the idea of another child, but resigned to the fact that she might never have a daughter.
