One Direction will take to the stage tonight during the Apple Music Festival.
The pop giants will play the Roundhouse in Camden with special guests Little Mix.
Niall Horan tweeted his excitement about the gig, writing: "really can't wait for the apple music festival tomorrow at the roundhouse. My favourite London venue ... Looking forward to seeing you all".
Last month the band hit the headlines over rumours about their future - shocking millions of devoted fans.
But Horan and his bandmate Louis Tomlinson told fans on Twitter the four-piece, also featuring Harry Styles and Liam Payne, would just be taking a ''break''.
It came after a report in The Sun that the pop stars are set to go their separate ways in March.
A source told the tabloid the band will not tour their fifth album and will instead part company for a year because they want to focus on solo projects.
In a series of tweets, Horan, 21, told his 23 million Twitter followers: ''Ok so lots of rumours going round. We are not splitting up, but we will be taking a well-earned break at some point next year.
''Don't worry though, we still have lots we want to achieve! Can't wait for you to hear all the new music we have for you and to perform some new songs as the (tour) continues. Love you all.''
In March, the band vowed to continue as a four-piece after Zayn Malik's shock departure, which he said was so he could live like a ''normal'' 22-year-old.
Both One Direction and Little Mix found fame on The X Factor with the boy band having gone on to enjoy global success, acquiring millions of fans who are known as ''Directioners''.
Little Mix, who won the ITV talent show in 2011, have also had success on both sides of the Atlantic.
The bands have been linked due to former One Direction star Malik having been engaged to Perrie Edwards from Little Mix.
But reports that the pair had split emerged in August.
The pop star duo got engaged in 2013 but had never publicly announced a wedding date.
The Apple Music Festival, which offered fans the opportunity to win free tickets to see their favourite performers, has already featured concerts by Ellie Goulding, Take That and Carrie Underwood.
