CBB bosses recently gave Chloe a telling off for what she did to John, 25, but that didn't stop her as she can be seen taking things one step further in the latest episode, while her housemates look on in shock.
John – who doesn't seem particularly phased by Chloe's routine – sat still on a chair while Chloe writhed around all over him, with her even pushing her breasts into his face at one point.
John eventually ended up on the floor, as bikini-clad Chloe straddled him and bounced up and down.
Her latest actions come after she was called to the Diary Room, with Big Brother telling her she was making "uninvited physical contact" with her fellow housemate.

She was told: "Today in the bathroom with John, you lifted up your towel and rubbed your naked bottom against his back.
"This was uninvited physical contact when you were naked. Chloe, invading people's personal space when you're naked is unacceptable and Big Brother would suggest that you refrain from this sort of behaviour in the future."
The 21-year-old replied: "Sorry, I was honestly having a bit of a joke," before protesting: "He fake tans my bum all the time."
Big Brother continued: "John has not suggested to Big Brother that he had a problem with your behaviour. Big Brother always speaks to housemates if Big Brother thinks that Big Brother needs to."
