The singer, alongside fellow contestant Lucy Spraggan, was asked to leave the 5-star hotel yesterday after a drunken night out resulted in him flashing his bum outside the entrance.
"Oh god, the hotel were not happy with that kind of press," Clark told Heat magazine.
"I'm holed up in a hotel in Wembley for five days. I've got to behave myself.
"I can't believe it. I was so drunk, but I said I'd do it and I f**king did it. The X Factor team warned me not to but they love it really."
Spraggan previously tweeted: "Me and @RylanClark are partaking in a small vacation from the hotel for a few days. Our most sincere apologies for our #beerfear behaviour."
Clark recently confessed that he has "no expectations" of winning The X Factor, saying he's come to terms with his "joke act" label.
