The X Factor 2013 live tour hit the O2 Arena for the first time last night, and it was an epic show.
For many of the stars, such as Union J and Jahmene Douglas, it was the location of their original audition in front of the judges last year.
Returning this time they had thousands of fans chanting their names and singing along to their performances, as they belted out tracks from the show.
Jahmene tweeted after the first show: "Wow .. The London O2 is an incredible venue and the crowd was alivvvveeee !! Loved every bit ! Thank you all so much 🙂 <3 #keepsmiling x"And Union J added: "Wow the o2 was amazing tonight. Nice to be back there again and seeing how far we have come since then. Seems ages ago. JJx"Still recovering from his tattoo experience in Liverpool, Christopher Maloney added: "thank u to everyone at the 02 arena! what a lovely crowd! so loving xx :-)"
An extra date at the venue has been added tonight, although it seems some of the stars aren't getting much rest!
Celebrity Big Brother winner Rylan Clark revealed to his fans this morning: "Off to @loosewomen in a bit! Xxx"
No wonder why he's so worn out!.
