Chart stars One Direction were delighted today after their new single Live While We're Young hit the US number 1 spot, to become the fastest-selling single by a UK act.
The sales tally of 341,000 copies in the space of a week is the biggest ever in the US for an overseas act.
The achievement comes as the group failed to top the UK charts, making it to just number three, with Rihanna taking the number one spot with Diamonds. And it is expected to drop out of the top five of the Official Singles Chart on Sunday.
But the band were thrilled by their latest US success. Niall Horan said: "We're so happy with the success of the single in the USA and can't wait for everyone to hear our new album. Thank you to all the fans once again."
The single has also proved a popular draw online. The promo for the single became the most viewed video within 24 hours on video site Vevo.
Earlier this year the quintet became the first UK group to enter the US Billboard chart with their debut album, Up All Night.
