Chart stars One Direction have amassed so much cash they have soared into an under-30s British rich list – displacing Harry Potter actor Rupert Grint.

The former X Factor quintet are listed at number five in celebrity magazine Heat’s annual Rich List, with a combined worth of 26.33 million pounds, while Rupert who held the spot last year is down to seven.

However, another Potter star Daniel Radcliffe continues to dominate the chart for a further year with his 53.33 million-pound fortune.

The list – based on estimates of their financial dealings – sees British Twilight actor Robert Pattinson move up to number two with £38.73 million, pushing Keira Knightley into third spot with 32.7 million.

Unsurprisingly, Adele has had a massive rise – up 10 places – and is said to be worth £26.06 million.

One Direction, like Adele, have become worldwide stars and conquered the US earlier this year with their debut album Up All Night.

Girls Aloud are estimated to be the biggest earning group under 30 with a combined £35.16 million, however they have been listed individually because of their individual careers, despite reuniting to celebrate their tenth anniversary.

Heat editor Lucie Cave said: “One Direction will be thrilled to hear that they’ve burst into Heat’s Rich List as the highest new entry at number five. Like any pop stars they’ll be after the number one spot, of course, but if they keep going the way they have been, that might be a reality in 2013.

“In these financially tough times it’s good to know that at least somebody is rolling around on carpets woven from gold-plated 50-pound notes – which is why Heat is delighted to reveal our annual countdown of the richest British celebs under the age of 30.”
