The entrepreneur brushed off allegations that he avoided the annual end of series party because he didn't want to be in the same area as Lady C.
However, Duncan directly contradicted this via Twitter today, saying the allegation that been "made up" and was not true.
Duncan clashed with Lady C in the jungle and has continued to voice his thoughts on her via Twitter, calling her a "first class bully". He also reacted to her tell-all interview last week, saying: "Tony Hadley & I will continue to rise above, remain dignified & nor respond to the disgusting comments in her story."
He told ITV's Good Morning Britain last week that the constant rows with Lady C started to affect him in the jungle. "I did almost have a breakdown at the end when Lady C was popping at me all the time. Then she left, and everything, it was good again."
