Brooklyn Beckham is dating the daughter of an aristocrat.

The 14-year-old son of David and Victoria Beckham reportedly made it ''official'' with his girlfriend when his family moved back to the UK from Los Angeles earlier this year.

An insider said: ''Brooklyn is smitten.

''Once the problem of distance was sorted, they decided to make it official. They've been friends for years.''

The Daily Star Sunday newspaper - who claim they know the identity of the 15-year-old girl but are respecting her privacy - has revealed she plays lacrosse at the elite private school she is a pupil at near her London home.

While Brooklyn has been teased by his brothers Romeo, 10, and Cruz, eight, both are said to be ''happy for him''.

The source added: ''He's been getting a lot of stick from his brothers but they're really happy for him.''

David and Victoria - who also have two-year-old daughter Harper - want their children to ''lead a normal life'' and the retired soccer star has admitted their eldest son is starting to want to branch out on his own.

He previously said: ''Brooklyn is now at the age where he wants to do things and go places and you have to hold him back.

''But to be honest, with our children we let them do 99% of the things they want to do. We want them to lead a normal life.''
