The Miami-based fetish model didn't hold back when talking about her doomed relationship with Kirk in her CBB video package ahead of entering the house tonight.
"I don't want to give any publicity to the little s**t," she said.
"It was a whirlwind f**king nightmare. He is going to f**king hate me..."
As Cami made her way into the CBB house, host Emma Willis tentatively pointed out that things between Cami and Kirk clearly didn't seem to be too good but had ex-CBB star Kirk given Cami any house pointers...
"Honey, I haven't spoken to that man in a long time," replied Cami.
Cami and Kirk enjoyed a well-publicised and whirlwind romance in 2013 that included a proposal at a Wagamama restaurant in London and a promise by Cami to leave her native US and set up home in the UK.
But just six months later it was all over.
Cami later exclusively spoke to Reveal about the break-up, saying: "Kirk needs to grow up in many ways. I wasn't allowed to work, so I didn't have my own money, and I had to ask him and he'd give me an allowance.
"He had an issue with everyone I wanted to hang out with, so I only had three friends of my own."
So far Kirk hasn't responded... but we're predicting he will!
