Anamélia Silva and Kay Lovelle didn't see eye to eye in tonight's Big Brother 2018 highlights.
After pairing up for a task, personality clashes are becoming apparent between the new housemates.
This evening's episode saw Anamélia and Kay involved in a heated row in the bedroom, as Kenaley Amos-Sissons tried to act as peacemaker.
It began as Kay confronts Anamélia over her 'harsh mannerisms' in the task.
Anamelia reacted: "When I'm competing I'm going to be this way. Under competition, something happens in your mind You're going to be that way. That's how I am in competition. "
Kay replied: "It's jarring. It is intimidating. It doesn't mean we get rude to each other."
Anamelia reacted: "God made me this way, God made me full of passion!
"If you don't like that, you don't have to be around me, there is 12 other people!"
Kenaley attempted to calm the situation down: "I think you two... Kay's just a bit different..."
"But I don't have to change, she doesn't have to change either, but she's asking me to change," Anamélia said.
Kay said: "Not change but for me, it's harsher mannerisms to what I'm used to, you know."
"What you're used to, but I'm not used to people like you," Anamélia reacted.
Kenaley commented: "She's [Kay] not necessarily saying that you're wrong, it's just that sometimes you should be mindful because she is different. Again, maybe there are things she could do 'cause why should you change?
"But she's being honest with you, so don't take it the wrong way."
Anamélia concluded: "And I've taken that, I've respected that, I've apologised but one thing I'm not going to do is change. I'm not going to do that."
Elsewhere in tonight's show, it's not all war between the housemates.
Cameron and Lewis F's friendship is blossoming, while Brooke gets emotional after a chat with Tomaz and Cian.
She told Big Brother in the Diary Room: "I've got to know people I've not spoken to at all tonight. I've had a really emotional conversation earlier with Cian and Tomaz about things I couldn't open up to about anyone else... cause we're the only three gay people in here."
Meanwhile, the Big Coin tasks continued with housemates able to reduce one another's totals in a new twist.
Big Brother 2018 airs Sunday-Friday nights at 10PM on Channel 5.
