Chris finished third at the weekend and despite the series now been over, has been the centre of week of controversy.
Reports in the past few days have suggested Chris clashed with the other finalists backstage during the weekend’s final, branding Carolynne Poole a “c**t” during rehearsals.
Chris subsequently went missing for Sunday’s final after finishing the show in third place the day before.
Speaking to Alan Carr's Chatty Man, Olly said: "To have been booed every week must have been hard. It even happened to him at the final and I was like, ‘Come on’.
“He is changing his life, even if he has become a complete...
“He is still a nice guy.”
In the interview, to be aired on Channel 4 on Friday night, Olly also reveals how he and Caroline spent over £800 celebrating the end of the series in Manchester at the weekend
“I can’t drink at the moment, as I am still recovering from that night," he said. “It was insane. Lots of drinks were consumed and it was pretty messy."
And Olly revealed: “One of my straight mates snogged Rylan too!”
Meanwhile, Chris took to Twitter last night to beg the haters to be back off.
He tweeted: "plz stop online abuse,all I done was follow my dream,coming 3rd was an achievement.feel gutted I didn't win an im unwell right now, plz xx "
