Calum Best kept quiet about his girlfriend because he didn't want to "jeopardise" his participation in 'Celebrity Big Brother'.
The 34-year-old hunk has been dating former 'Made In Chelsea' star Ianthe Rose Cochrane-Stack for the past six months, but has revealed he kept the relationship secret because he thought it would make him less attractive to the show's bosses.
Calum explained: "I thought about all sorts of stuff in the house and it was definitely explicit. I have changed but I'm always going to have a naughty side. So I went to see my girlfriend the day after the final and we ... hung out.
"She's cool with what happened in the house. But going on the show, I was conscious, like a few others, that I wanted to be 'single'.
"'Celebrity Big Brother' wouldn't touch me for years and I've worked hard for this chance so I wasn't going to jeopardise it by saying, 'I'm taken.' I had to walk in by myself and leave by myself."
Calum - whose reality TV past includes an appearance on ITV's 'Celebrity Love Island' - did get close to American glamour girl Cami Li and has admitted she is "his type" of girl, but the fact that he was able to resist her advances in the house is proof of how he has changed since his hard-partying 20s.
He told The Sun newspaper: "Cami was cool and I had a lot of time for her. But I think I did myself proud there because people expected one thing and didn't get it. When I was 24, and on 'Love Island', things might have been different. But I'm 33 now and I'm not that guy who chases girls on national TV."
