Kav starred on the Channel 5 reality show with Katie earlier this year, but has said in a new interview that he feels let down by the outspoken TV personality and former Apprentice star.
Speaking to Inclusive Networks, Kav said he saw a "different side" to Katie once the show came to an end in February.
"I'm disappointed in Katie Hopkins a little bit as we got on well in the house and I saw a different side to her and I've not heard a thing from her since we came out," he said. "All I've seen is this pantomime."
Kav said he is good friends with Cami Li and still speaks to Calum Best, but feels let down by Katie.
"I feel a bit frauded as when you're in the house you share things and confide in people, spending hours chatting," he continued. "Things were really tense in the house too that you build friendships with people much quicker than you would in the real world."
Kav was evicted in seventh place on CBB. Katie Hopkins was runner-up, with Katie Price being crowned as the winner.
