David and Victoria Beckham's new daughter is believed to have been named after a Disney character.

The naming of Harper Seven, who was born in Los Angeles on Sunday (10.07.11), is thought to have been largely influenced by her three brothers - Brooklyn, 12, Romeo, eight, and six-year-old Cruz - who wanted to call their sister Harper Finkle, a character played by Jennifer Stone in TV show 'Wizards of Waverly Place'.

A friend of the couple told The Sun newspaper: "The boys love 'Wizards of Waverly Place' - and have been very vocal in helping to name their new sister.

"David and Victoria think it is a lovely name. The whole family is pleased with the choice - the boys are very happy.

"Seven is something they had talked about. They were still not certain when the baby was born but it all seemed to fall into place.

"She was born in the seventh month in the hour of seven and weighed seven pounds. It just seemed right. David is keen on the meanings and power of numbers. We all hope it will bring her luck."

The soccer superstar also wore the number seven shirt when he played for Manchester United and captained the England team.

Following the arrival of Harper, Victoria has told husband David they are not having anymore children, insisting their family is now "complete" after going through a pregnancy that left her with back pain and bunions.

A source said: "With three great boys and now a beautiful girl Victoria is insisting their family is complete.

And a friend added: "Victoria is determined not to have to go through that again."
