When Rylan made a tweet about not being sure as to what he is next going to do, I think he was referring to either doing BBOTS or Xtra Factor. I can only guess that he was waiting to see if Olly had officially quit before he accepted BBOTS. Now that Olly has quit Xtra Facor, he probably will do that instead because obviously it would be better money. I'm only speculating but it definitely looks likely.
From the forums reaction to Rylan maybe doing BBOTS, I'm thinking that everyone would rather he do Xtra Factor and stay away from big brother?
