The teen idol took to Twitter after being told that last night's show focused on Demi Lovato's young adults and Simon Cowell's groups categories - with Reid's over 25s getting relatively little air time.
Biebs tweeted: "Heard we got used for ratings according to twitter and we arent even on until tomorrow? @xfactorusa could of just told us."
But he wasn't dwelling on his disappointment - revealing that his fans had cheered him up.
He continued: "About to see my fans...my beliebers...and it's gonna BE ALRIGHT. #showtime #CANADA."
The star yesterday slammed a thief who stole a camera and phone containing his "personal footage".
