Expressandstar.com reports, 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.
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.
