The house had been split into two teams, The Elves and The Reindeers, and they were told by Big Brother that they had to perform a dance every time they heard their team's music being played into the house.
Bear decided to rugby tackle Marnie in the garden and prevent her from reaching the Elves' workshop when it was their turn to dance. Frankie then tried to help Marnie and told Renee that he had been hurt by Bear in the process - that ultimately led to Renee snapping at Bear.
She told him: "I'm a disgusted elf. You just take advantage of anyone and everyone and it's so disappointing. You are a complete f**king a*sehole. That is it. And I'm really sorry but I can't be bothered with anymore making up this and that, it's so extra. And I don't give a f**k if it's dramatic, and I don't give a f**k if you laugh at me, because let me tell you something if you were in f**king America buddy, you wouldn't be laughing because your jaw would be on the back of your f**king head."
"Why don't you keep it real?" he asked.
Bear then continued to press Renee's buttons and hit back at her: "That's quite aggressive elf behaviour..."
She replied: "I don't give a f**k if it's aggressive or not. You're lucky. I don't care, you've abused everybody."
Marnie assured Bear that she hadn't personally been offended by him tackling her, while Big Brother called Renee to the Diary Room to calm down.
Speaking to Big Brother, Renee broke down in tears and said: "I just can't do this. This was not the way I was raised. It's mean."
Not wanting to face the camera, she turned her back to Big Brother and cried.
When she left the Diary Room, Renee told Bear that she wouldn't be defending anyone else going forward - after getting annoyed that Frankie had already made up with Bear, despite Renee calling Bear out for his actions on his behalf.
She said: "Going further you won't hear snap for anybody else. I have a certain way about me and I always protect..."
Insisting it wasn't a big deal, Bear interjected: "Renee all that happened... it is a silly task. Joking about, I rugby tackled Marnie, Frankie got involved... I don't really care about it, but you make a big fuss about it and it's embarrassing. It's just a dance by a chair, the same as a dance by a sleigh."
"I couldn't give two flying f**ks," Renee responded. "But when someone comes in here and says that you have hurt them, I can only react, I didn't see it, I'm going off of what my friend said."
The task was later won by the elves, meaning that they have been given the reward of choosing TWO nominations in a nominations twist.
Ahead of this week's CBB final, Renee, Frankie, Marnie and Aubrey O'Day can pick two of their fellow housemates to face the last eviction before the final. Bear, Katie Waissel, Ricky Norwood and Sam Fox, however, can only pick one.
Bear is eternally nominated and will automatically face the public vote.
The latest nomination twist comes after both Lewis Bloor and James Whale left the house in a double eviction.
CBB continues at 9pm on Channel 5.
