Meanwhile, the boys have been forced to cancel a concert in Belfast after Liam fell ill. Fans were left devastated as the announcement was only made moments before the four were due to get on stage.
One witness according to BBC News said “hundreds” of young girls and women were left weeping following the announcement.
Concert promoter Aiken PR did confirm that the show was cancelled, but ensured fans that the illness was “not serious”.
Fans are being told to hold onto their tickets and wait for more information, with a statement expected later today (October 21).
Taking to Twitter, Harry wrote: “Deepest apologies to everyone at the show tonight in Belfast. Very disappointed, but unfortunately these things happen. We're very sorry.”
Louis added: “We're so so sorry for what happened tonight, it was out of our control! Lots of love to Liam and thank you for being so understanding!”
