On the program, he had asked Diana to be his girlfriend and even professed his affection for her.
Kaz reveals that not only have he and Diana split while on the Reality with Will Njobu podcast, but they have also visited other people since the show ended.
"Yeah, me and Diana... we're talking there's a lot that happened," said the show's host Will Njobu.
"Unfortunately, we haven't had a discussion about it. It was so intense in there." He added that coming outside of [the villa] was a different story.
"There's a lot more going on, going back to work, and family concerns," said the author. "We saw less and less of each other," he added.
He then stated that he has been seeing other people since the break-up.
"I've had communication with girls, and I've spoken to a couple of people, but it hasn't gotten to anything serious," he said.
Kaz replied when the host asked him whether or not they're still together. "We're not, but we're excited to see what happens in the future."
