Former Celebrity Big Brother winner Katie hasn't hidden her dislike of Jemma and continued to hit out at the current housemate during Bit On The Side last night.
And with Bit On The Side airing live from inside the house, Jemma heard everything.
After the spin-off show wrapped up, Jemma took aim at Katie and told the other housemates: "I'm in this house now, you're not.
"It's my turn to be in this house if you want to come to me, come to me in the real world to my house and we'll speak about it.
"But to say that behind a bit of glass, I just don't understand what her aim is for it apart from a a bit of attention. I don't get it."
She continued: "If that is what she wants a bit of attention then cool, she's Katie Price, she'll get attention wherever she goes.
But what does she gain? I can't respond to her from here.
I know she wants people to not like me, I used to live with her, I know her.
"If you want to feel big and clever by coming at me from a side of piece of glass, the whole film crew and security everywhere, where you s**t ain't going to go down... if that makes you feel like a bad b***h then carry on but I think it's pathetic."
Despite campaigning to 'Get Jemma Out' all series - including last night - Katie did end her appearance on Bit On The Side with a positive note.
Putting aside their 'personal' issues, Katie said: "I'll just say, I know we have our beef, or whatever...
"But generally, she has done well to be in the final, and everyone deserves a chance, I just have personal stuff with her.
"So good luck to them all!"
Celebrity Big brother 2017 concludes live tonight at 9PM On Channel 5.
