His mum and dad are worth nearly $400 million but Victoria and David Beckham's son Brooklyn is reportedly working in cafe to learn the value of money.

The 15-year-old is working in a coffee shop near his family's London home at a minimum wage rate, according to Britain's The Sun on Sunday.

A source has told the publication, "Brooklyn has got the world at his fingertips and could have a life of luxury if he wanted - but the lad is not that way inclined.

"Brooklyn and his three siblings (Romeo, 11, Cruz, nine, and Harper, two) have all had a great start in life - much better than most.

"But David and Victoria want them to know what hard work is like."

Brooklyn has already started earning his own money - he landed a top modeling job when he appeared on the cover of Man About Town magazine earlier this year.

Fashion designer Victoria and sports superstar David are estimated to be worth $US336 million ($A389 million).
