Just hours after he had taken to the 'X Factor' stage to perform his debut single 'Just Hold On' with Steve Aoki, the 24-year-old singer was spotted at London's Cirque Le Soir with his sister Lottie and his bandmates Liam Payne and Niall Horan as they all had a drink in remembrance of Johannah Deakin, who passed away earlier this week after a secret battle with leukaemia.

A source told the MailOnline: "It was family and friends drinks in Cirque, all paid for by Johannah's husband Dan. It was a celebration of her life and his X Factor performance. It was a very emotional night."

Louis was joined by Niall, Liam and Harry Styles in his dressing room backstage at 'The X Factor', with the group having flown in from around the world to be with him.

An insider shared previously: "Harry, Niall and Liam all came down to X Factor to support Louis. They all were backstage with him supporting him. It was a lovely moment - and shows the unity of 1D. First time all back together in a year.

"It was a lovely touching moment backstage and they all came to support Louis during a horrible time. Niall even flew back from New York."

Following his performance, Louis took to Twitter to admit it was "harder than he ever imagined".

He wrote on the microblogging site "That was harder than I ever imagined. I want to thank everyone around me and all of the amazing fans out there that made that so special! ...

"Feeling so much love around me and my family . Mum would have been so f***ing proud ( sorry for swearing mum ) love you ! ... Also @steveaoki , you have been such a rock and inspiration throughout this ! Pure talent and a real gent ! (sic)"
