However, the Geordie gym instructor insisted that they will remain friends in the outside world despite their bickering in the house.
Speaking to Emma Willis on Big Brother's Bit on the Side, the star divulged: "He is a likeable lad, and he is a mate and that, but when he has his mood swings, you just feel like punching his head in.
"We have smoothed it over. I've always had to be the one to apologise. He would've taken it for the full nine weeks if he had the opportunity to. But he's a good lad."
The 27-year-old admitted that he felt as if he was romantically involved with Allard-Morgan, following the pair's falling out.
Mckray added: "I feel like I've been going out with him more than Lou because I'm up and down and it was more of a roller coaster."
