The former X Factor star and Celebrity Big Brother winner told Digital Spy at the Loaded Lafta Awards: "I wouldn't ever do that. I can't believe it. I think it's disgusting. Absolutely terrible.
"I'm not being funny, but I came straight out of the Big Brother house, had 45 minutes' sleep and I was bang on time for my tour the same day - so he could have done the f**king same."
On his upcoming career, he said: "My dream would to be to have a number one hit, but that's all it is - a dream… there's a lot going on at the minute, lots of discussions. I went on X Factor to do music, that's what people forget, so if something comes up, great, but if not then I'll stick to telly.
"I'm taking this one step at a time. I don't want to be one of those muggy [reality stars] who opens a shop and does everything in the first five minutes and it all f**ks up. I've got half a brain cell on me."
On who he'd like to see on the next X Factor panel, he said: "I'd love to see Sharon Osbourne back. I think she does a great job and it's time she returned. And any Spice Girl - they're always nice to add to the line up. Geri's my favourite."
Remembering Geri's infamously panned stint on the show last year, he said: "I think she'd do a great job…
"I know there's a lot of rumours flying about me joining The Xtra Factor, but I don't know whether Olly [Murs] and Caroline [Flack] are doing it. Things don't get decided until like the day before. I'm flattered that my name's been brought up, and if the opportunity comes along, then we'll discuss it."
Would he ever go back on the show to guest judge? "If I was to, I think that would be the end of X Factor, let's be honest. I think I'm a bit more Britain's Got Talent."
On his time in the CBB house, he said: "I'd go straight back in. I'd spend the whole year in there. It's so much easier than it is out here - even with Heidi and Spencer."
Commenting on controversial comedian Frankie Boyle - who recently fell out with his friend Katie Price - he said: "If you don't like what someone's saying then don't watch it or listen to it.
"Frankie Boyle's said stuff in the past that's got him into trouble, and he says stuff that most people don't agree with but if you don't like it, don't f**king listen to it!"
On the recent Twitter row between Price and Kelly Brook, he said: "I still don't know what actually went on there. I haven't spoken to Katie or Kelly about it. I think Kelly's beautiful and she's got an amazing figure. I'll have to have a word with Kate about her."
Openly a fan of Botox, he said of his looks: "I'm nearly finished with what I want done with my face. Nearly. There's one more thing I want. You'll probably see what it is over the next few weeks!"
And on his new TV appearance with Keith Lemon, he said: "I'm on this series of Celebrity Juice. I'm not the new Jedward - I'm the new Rylan. Jedward might be making an appearance as well, you'll have to watch."
