Heat have revealed their richest Brits under the age of 30, with very few surprises. Daniel Radcliffe, Emma Watson and Rupert Grint, the starring actors of the Harry Potter movies, are all in the top ten, which is topped by Radcliffe, with a cool $85m. Not bad for a 23 year old.

However, the real big winners in this year's list are One Direction, who have collectively amassed $42m. Last year they were no where near the top 100, let alone the top ten, yet that figure brings them in at number 5. The band, with an average age of 19, have conquered America, which is where the big bucks are coming from. With their single 'Live While We're Young' One Direction broke the record for the fastest selling single by a British act in the US. Not bad going for a band that was formed just two years ago. 

Adele has jumped ten places to number 6, which marks an excellent year for the singer-songwriter, becoming a Mum for the first time and being the voice of the new Bond film. Robert Pattinson is in at number 2 with great thanks to the Twilight Saga. Keira Knightley takes third place with $52m. MTV reports that Leona Lewis, Cheryl Cole and Katie Melua all make it into the top ten. With One Directions's continued successes such as they have seen this year, it'd be no surprise to see the young group hitting the top spot next year
