'Queen of Pop' Madonna's son Rocco and soccer star David Beckham's son Cruz are predicted to become the richest celebrities in UK when they grow up.
Rocco Ritchie, nine, and Cruz Beckham, four, are tipped to have the most earning power in a new report compiled by Cartoon Network.
The report assessed the estimated worth of today's celebrity children in 20 years time, Contactmusic reported.
Rocco, son of the 'Celebration' singer and film director Guy Ritchie, topped the four categories in the report - star quality, likely inheritance, talent and love of the camera - getting ratings of ten out of ten for each.
The report also estimated Rocco to be worth 376 million pounds before he reaches 30.
"Rocco will earn a fortune from his mother and a fair bit from dad. But it's the other three rankings that power him to the number one place," Celebrity expert Mark Frith said.
Cruz, whose mother is former Spice Girl-turned-fashion designer Victoria Beckham, beat siblings Romeo, seven, and Brooklyn, ten, to second place in the list.
Both Rocco and Cruz scored highly because they have been spotted dancing at their mother's concerts.
None of Rocco's other siblings, sister Lourdes and adopted brother and sister David and Mercy, featured on the list.
British royals, William and Harry, came ninth and tenth on the list with estimated fortunes of just under 200 million pounds each, but were both awarded zero out of ten for showbiz talent.
