But it seems as though the boys - or at least whoever posted the messages to their Twitter account - had a sudden change of heart.
The messages were wiped from the account within an hour, but this being the internet once it's out there, it's out there.
"We felt betrayed by housemates with their invalid reasons for their nominations and when they stereotyped us as something that we are not," the messages began.
They went on to take aim at "contrived housemates" who "set up storylines together".
The rant continued: "The housemates being called intellects and knowledgable were far from it couldn't even string 2 sentences together 90% of the time.
"A bee wouldn't sting you as much as these housemates literally stung us... lol give us a beehive any day. We knew in our heart we were around people that were hiding behind a glass of drink or a cigarette hardly any genuine emotions
"Like there was no depth to them at all! We were literally the ocean and they were a little poodle of water. There was no meaningful conversation like I never heard such rehearsed monologue stories and interactions in my life."
They added: "So many harsh words flew from the gang todays us... talk about making someone feel uncomfortable and welcome."
"Glad we're free and can now write down the truth," the messages concluded.
It's not 100% clear if Jedward themselves actually wrote the the string of messages, which were deleted within minutes.
