One Direction have shattered video viewing records on entertainment website VEVO after 10.7 million fans flocked to check out the band's latest promo in one day. The group debuted its Best Song Ever video on Monday (22Jul13), and the bandmates were stunned when the promo quickly became VEVO's biggest 24-hour hit ever, beating a record Miley Cyrus set with We Can't Stop a month ago. In the video, Harry Styles and his pals play caricatures of people they have encountered in the music industry - Niall Horan and Louis Tomlinson play record label executives, Zayn Malik a sexy assistant, Styles a marketing man, and Liam Payne a choreographer. The promo also features clips from the boy band's new movie, One Direction: This is Us. Horan has taken to Twitter to thank fans for helping the band break a new record. He writes, "Wow! You guys broke the vevo 24 hour record! Wow! Thank you so much! Love you lots!"
