And it's fair to say the incident isn't dealt with quietly.
In the bedroom, Jedward walks in on Nicola changing in the toilet and they immediately start to argue. Calum speaks up: “All you do boys, next time is apologise for walking in. It’s a simple one, it can be resolved.”
Afterwards, Nicola is unhappy about Jedward walking in on her whilst she was changing in the toilet; “I was standing there with no trousers on! They just walk in! I hate s**t like that! Disrespect! They have the right to walk in on me as I’ve been a Page 3 girl? They’re horrible.”
Meanwhile, Jedward are talking about Nicola in the diary room; “She has it in for us! Always nominating us!”
Later on in the evening, John and Nicola start to argue again. He say: “Don’t talk to me dumb blonde! That’s a sly remark!”
Nicola replies: “Why are you approaching me like that? You do not intimidate me!”
John adds: “You’re a drama queen! Mean girl! Trouble maker!”
Calum gets involved and he and John then begin to argue. Calum shouts: “Grow up! F**k you yeah! I was your buddy and now I’m not. Be respectful.”
Once things have relaxed, Calum is in the smoking area talking about Jedward: “I’m a cool calm collected person, they are riling me.”
Jedward are back in the Diary Room talking to Big Brother about Nicola: “This woman is a walking fake reality star who wants drama…we are not big headed, I haven’t changed my bed sheets in six months!
"She is literally the worse housemate to live with. It is what it is.”
They continue: “Then we have Calum Best who is trying to make out he’s a gentleman who is covered in tattoos…now that Spencer and Heidi have gone, it is on.”
After, Calum goes to the Diary Room and tells Big Brother: “We know Jedward have a core fan base…they are getting so arrogant. F**king rude! I want to like John and Edward but they have no respect…horrible housemates.
"I don’t really like either of them; they are 25 year old men that don’t have an ounce of men in them!”
