American model Cami, 26, told fans over Twitter that she was no longer with Kirk and has since returned back to Miami, Florida.
Taking to Twitter, Cami revealed: "Kirk and I are done. Sometimes your best isn't enough when battling against someone's demons."
Kirk, 25, has not publicly commented about their relationship since Cami's tweet. Reveal contacted Kirk's rep who said: "We can confirm that Kirk and Cami have split. Kirk is not willing to comment on the matter."
The reality star did, however, cryptically write on his Twitter account over the weekend: "I never wanted it to be like this!!!"
He added last night (24 November): "Learn from yesterday, live for today, hope for tomorrow."
Just last week, Kirk exclusively told Reveal that he decided to put his wedding to Cami on hold because of work commitments, but his decision had left Cami devastated. The pair originally set a wedding date for 25 January 2014.
He told us: "When I told Cami I was cancelling it, she didn't take it lightly. She was gutted to begin with. She was upset about it initially but I want our wedding to be the best.
"I only want to do this once and I want to spend the rest of my life with her, so I said, 'Let's not rush it, let's get it done around my schedule.'"
Speaking about his love for Cami, Kirk continued: "I thought I'd been in love with girls before but I've never had any of the feelings that I've got for Cami.
"She's really smart. She was studying law in America and she has a very good sense of humour. That's what made me fall in love with her in the first place, she's just like me but with boobs!"
Kirk and Cami, who announced their engagement in July, enjoyed a long-distance relationship in the summer before Cami uprooted from Miami to live with Kirk in the UK.
