Anamelia Silva and Isaac Jagroop have locked horns on Big Brother 2018 already.
Fourteen new housemates entered the Big Brother house on Friday for the last ever series.
On launch night, Big Brother announced a new twist called the 'Bank of Big Brother', involving Big Brother's new currency 'Big Coin', which would play a "very important" role in the series.
Big Brother explained that throughout the series, housemates would have the opportunity to win, earn or discover Big Coins. These could buy privileges, luxuries, and experiences, as well as being used to change the fate of the game.
For the first week, Big Brother announced that there would be no nominations and instead the three poorest housemates with the fewest Big Coins will face eviction.
"It's Survival Of The Richest," they said, before a load of coins descended from the ceiling.
As the coins came crashing down, housemates raced to grab as many as they could and it led to clashes between some of them.
Anamelia rowed with Isaac for 'stealing' her money and snapped: "Don't touch my f**king coins, put my coin back."
"Who the f**k steals from other people? Like why would you do that?" she then ranted at him. "I'm not expecting everyone to be like me but I think that is natural for a person that like, if I am the way that I am, then someone else is like the opposite, you get quite shocked.
"Cos I was like 'How could you do that?' Cos I would never be able to do that - like, ever."
Isaac responded: "I just didn't think it was a big deal whatsoever."
Trying to calm the situation, he added: "I don't want to get off on the wrong foot, I just met you."
Anamelia said she wanted to play the game with "integrity", saying: "I don't want to take somebody else's. Whatever I've worked for and I earned, it's mine."
But Isaac didn't seem too interested in "integrity", replying: "It's just a game at the end of the day."
Big Brother airs Saturday-Friday nights on Channel 5 at 10PM.
