The pair came to blows over dinner as Scotty T prepared a Chicken jalfrezi for the house.
While he was busy cooking that up in the kitchen, Megan McKenna decided she'd help out by making a side dish of Bombay potatoes - what could go wrong?
Cue, somehow, a massive row between the pair.
"I can't be bothered, I'm not standing out there with him, he's so f**king controlling," ranted Megan in the bedroom. "I don't know why... he' doing his chicken jalfrezi but if I want to make a little side dish for it, why can't I make a little side dish?"
She later went out to the kitchen to confront Scotty T: "What is the problem, what is the problem about that?
"If you don't like it, don't eat it."
After bickering about how best to prepare the potatoes, Scotty eventually snapped: "You just make the tea."
"You're acting like a ten year old" responded Megan as Scotty stormed out of the kitchen and into the bedroom.
She added: "Oh my God, just because I want to make some f**king Bombay potatoes, because I want to make a side dish, I get that."
It will certainly go down as one of the most random arguments in Celebrity Big Brother history...
