It's just weird how it got, with so many characters fighting for storylines. TOWIE is a great show, but I couldn't see what storyline I was going to end up with - I think I've quit while I was ahead". He later went on to appear on Celebrity Big Brother 9. Norcross returned to the show in the first episode of series 7, but left once again in series 8 after claiming the show had changed too much.

He said, "My club is an upmarket venue where people come to drink champagne and feel spoiled, All these rows they keep filming don't show the club in a good light and I'm worried it's putting people off coming, which is the last thing I want. Allowing the Sugar Hut Honeys to be called slags is the final straw. I would never allow that to happen in my venue. I've had enough. I'm out." Norkross also banned producers from filming in his club "Sugar Hut" following his departure. Two weeks later, his son, Kirk Norcross, announced on Twitter that he had left the show for a second time, claiming it had changed too much.
