Cohen revealed that "nothing is off limits" for this iconic reunion and gave us a surprising news: the show won't be shot at one of their houses.

"We're not filming it at their house, we're filming it in a sound stage. It will look like a real reunion show that you know, and love and it's, this is something that I'd wanted to do for a long time. And then when they announced that it was their final season, I was like, 'we've got to do this. We have to do this the right way.' You know."

Phillips then asked Cohen if Rob Kardashian or Caitlyn Jenner will actually appear in the reunion and Cohen said:

"Unclear, unclear. I don't envision that Caitlyn will be there."

And Cohen also shared how the reunion came to be:

"I did approach them. I pitched it to them when I went to Khloé's house to shoot the interview for For Real. And then all I'd have to say was very receptive. And, I've spoken to Kim a few times since then. And I I've said to her, 'look, if we're going to do this, we have to do it. Right. Like it's, I need to go there.'

And then continued saying that Kim absolutely agreed with him on this matter.

"She's like, 'no, no, no, that's what we want. That's what we like about you. We want to go there. We want to do this.' And I have to say any time that they've appeared on, Watch What Happens Live, there has been no restrictions surrounding their appearance."
