Last night, as Cami appeared on Channel 5 in the current series of CBB, Kirk made a point of telling his fans that he was not tuned into the reality show.
Taking to Twitter while CBB was on air, he tellingly said: "All tucked up in bed watching #porridge can't beat a bit of @GoldTVChannel night all!"
US fetish model Cami arrived in the CBB house alongside 13 other famous faces last Wednesday night (7 January) and made no secret about her feelings towards Kirk.
Despite insisting that she "didn't want to be known as Kirk's ex", Cami told her housemates that he is a "little sh*t", adding: "It was a whirlwind f**king nightmare. He is going to f**king hate me..."
Since then, Cami has also spoken in graphic detail about a naked picture of Kirk which emerged on the internet shortly before she began dating him in June 2013.
In all, Cami and Kirk were together for six months - and even got engaged - before their bitter split in November 2013. While in the house, Cami has admitted that she hasn't seen the TOWIE star since their break-up.
Perhaps rather surprisingly, given everything that has been said, Kirk has remained tight-lipped about Cami's comments and has so far refused to rise to the bait. Or tune in, even!
