Rumour has it that the name Harper was chosen by the Beckham boys in homage to a character from the Disney TV series Wizards of Waverly Place, one of their favourite TV shows.
Apparently David used to read the books from the show to the boys when they were younger, and now they love to watch it on TV. The boys have also visited the show's set.
The programme - which stars Selena Gomez - centres around three young wizards and their friend Harper Finkle.
Hmm, so that's a theory for Harper. Shall we move on to Seven now?
Love the name or loathe it. Join the debate here.
Having waited so long for a little girl, did you think the Beckham's would choose something a little more girly and feminine?
Or do you like Harper?
