One Direction have been predicted to become the most successful band in the world with earnings of a billion dollars a year.
It is estimated the band will earn the record £611million amount during their upcoming Where We Are tour.
The 88-date tour will see the boys - Harry Styles, Louis Tomlinson, Zayn Malik, Liam Payne and Niall Horan - become the first act to perform three consecutive nights at the 95,000-seat Rose Bowl stadium in California.
A spokesman for the band told the Daily Star: ‘It would be amazing for 1D to climb to the very top of the tour league so early in their career.
‘That would be a phenomenal testament to the loyalty and support of their fans.’
Music industry insider Mory Brenner added: ‘You have to go back to 1964, when The Beatles led the British Invasion that turned American’s music industry upside down, to find anything close to the following they have.’
Their latest earnings are set to top the £447million record set by U2 for their 360° tour.
They could also beat the £339million earned by The Rolling Stones from their Bigger Bang shows.
One Direction were also the most popular artists last year in terms of music downloads, streaming and CD sales.
The IFPI, which promotes the international recording industry, named them Global Recording Artists of 2013 after they were the first group to debut at number one in the US charts with their first three albums.
Niall Horan, 20, said of the news: ‘Incredible news. It's great to have a chart that includes everything from iTunes and record stores, to YouTube and Spotify. Again a huge thank you to all of our fans for such an amazing 2013.’
Meanwhile, Harry Styles recently celebrated his 20th birthday with a party at girlfriend Kendall Jenner’s Malibu home.
