Katie H made the cutting jibe last night during the latest episode of the reality show and, understandably, it has not gone down well with Danny!
The housemates were taking part in a task involving their letters home and, as Katie Hopkins attempted to come up with a theory to save all the notes, she concluded that Katie P - who was in an adjoining room - wouldn't be clever enough to come up with the same idea.
Speaking to Michelle Visage, she said: "Let's remember, Pricey is thick."
Following her cutting remark, Danny - who is manning Katie's Twitter account during her time in the house - attempted to make light of the comment. However, it's clear he was riled!
"THICK? layers of fake tan perhaps.... #cbbkatieprice," he tweeted to her followers.
It was a big night for Katie, as she suddenly found herself up for eviction alongside Keith Chegwin, Cami Li and Perez Hilton.
In a special Live Bombshell episode, the housemates were shown footage of the most recent batch of noms before, unbeknown to them, the phone lines were opened for an hour.
Once the time was up, CBB host Emma Willis stunned the celebrities by entering the lounge and evicting Cami Li there and then!
Katie's brother has since thanked all the fans who had voted to save his sister from the chop. He tweeted: "Well Great British Public, thank you for keeping her in, it also means you get more of me on here for another few days."
Thanks everyone for your support this evening- final thought of the day...... "its nice to be nice" #cbbkatieprice— Katie Price (@MissKatiePrice) February 2, 2015
He later added: "Thanks everyone for your support this evening - final thought of the day...... 'it's nice to be nice' #cbbkatieprice."
At the end of last night's show, the phone lines were opened again and viewers can now vote for who they want to win.
But before Friday night's finale show, TWO of the CBB housemates will be evicted tomorrow evening!
Can KP make it all the way?
