While sitting in the kitchen with the other housemates, former Hollyoaks actress Stephanie had a few things to get off her chest about GC, who told her she was a "disgrace" the night before for kissing Jeremy McConnell while having a boyfriend outside the house.
"Gemma, just the person," she said. "Can you let me speak and then you can speak."
"Yes, I am messy," she continued, "yes, me and Jez are really close and we have our own things to talk about. Yes, I have been through a lot for a young age. I'm 22. The age of you is a disgrace. Don't ever think I'll be your lapdog and run around after you. Don't speak to me the way you speak to me. My own mother wouldn't speak to me like that, okay? Simba. With the fr***ing hair."
Gemma, who was making breakfast, said: "Please be quiet, Steph. It's not the time."
But Stephanie replied: "Don't speak like that to me in front of everyone. You should be ashamed and disgusted at yourself. What age are you and the way you've been acting in this house? I've said my piece."
Gemma stopped what she was doing and went over to Stephanie. "You don't bother me in the slightest," she told her. "You know that, don't you?"
Stephanie responded by putting on an Essex accent and doing an imitation of Gemma. "Go and have a strop," she added. "Go and be a diva. Be Gemma Collins."
But later on, Stephanie seemed to have a change of heart as she apologised to Gemma and said she was just tired, hungry and upset that Gemma had called her out about the Jeremy kiss in front of everyone rather than taking her to one side.
Gemma accepted her apology and the pair hugged.
On last night's show, viewers saw Stephanie being sent to a separate bedroom to calm down after a foul-mouthed rant against Gemma in which she told Big Brother she may punch her if she returned to the house immediately. She was given a warning for that comment.
CBB continues tonight at 9pm on Channel 5.
