When asked if they were a couple by OK! magazine, Peter said: "Yes we are. We're finally going out with each other."
And Jordan added: "We knew it was on the cards from the moment we were in the jungle. The chemistry was there."
They said they finally had sex not long before their recent holiday together in Cyprus.
And Jordan said: "He's certainly not an acorn! All those stories that girls have done on him, big deal, I'm not interested. If they say he's small, they're just bitter. He puts every other boyfriend I've been with to shame."
Peter said: "When the chemistry is so there from the start and you wait and you get to know each other, go for dinner and finally do what you do, it is one of the most beautiful experiences.
"Katie is so different from what I thought. No matter how wild a person comes across, people just want to be loved. I know I do and Katie does too. So I think for us it was more about making love than sex."
The couple said it was too early to talk about love but said they were both committed to making the relationship work.
Jordan denied rumours they were already engaged but added: "One day I want the full works with Pete. I want marriage, I want the kids. I've met enough guys and Pete is the one."
