He's one of the most famous athletes in the world — retired or not — and she's a former pop star and current fashion designer. So it's not surprising that David and Victoria Beckham are pulling in some tidy cash. But it turns out that thanks to the added incomes of their two eldest children — Brooklyn and Romeo, budding models both — the Beckham family is now worth more than the Queen of England.

According to a report by the London School of Marketing, the Beckham brand is worth at an estimated value of $771 million. The bulk of that comes from the family's three main corporate ventures: Footworks, valued at $228 million, the endorsements-happy Beckham label ($106.4 million) and the cryptically named Beckham Venture for Victoria's fashion work, which is valued at $91.2 million.

But the kids are helping, too. While there's no reported amount tied to what Brooklyn has made as a model or through his 4 million follower-strong Instagram feed, younger brother Romeo pulled in a cool $68,000 for one day's work on last year's Burberry holiday campaign. Not too shabby. Just imagine what they family will be worth when Cruz and Harper start pulling their weight.
