Basically, he announced who was going home before he'd been given the envelope with their name in. Apparently, he's not supposed to know prior to that. Hmm. That is dodgy.
Olly's just tweeted his apologies in regards to the incident.
I apologise to everyone tonight I made a massive f%#k up at the end. It was so tense!! I'm still learning & hope that never happens again!— Olly Murs (@ollyofficial) November 15, 2015
Yeah but... Olly. What actually happened? People need answers.
