Singer Niall Horan has overtaken fellow singer Harry Styles as the most popular member of One Direction on Twitter.
Horan, 23, has as many as 30.9 million followers on the micro-blogging website, leaving behind Styles, who has 30.8 million fans on Twitter, reports dailymail.co.uk.
However, the figures may not be a true reflection of their popularity, as Horan is notably more active on the social media platform than Harry, who doesn't tweets frequently.
Meanwhile, singer Louis Tomlinson has 25.2 million followers, with Liam Payne close behind him with 25.1 million.
Former One Direction star Zayn Malik trails all of the other boys, with a Twitter fanbase of 22.2 million.
