The former Ordinary Boys frontman was talking to his ex-wife about the time he walked off the music quiz when host Simon Amstell made fun of her.
Preston explained his reasons for returning to the house. "Obviously because of Buzzcocks and all that shit," he said, before explaining that he hoped to improve the public's perception of him.
Chantelle defended his reasons for walking. "You only did that because people were being horrible to me," she stated.
"Of course I did, no-one is going to do that while I'm around. I just regret going on that show," Preston admitted.
Chantelle insisted that Amstell was directing his insults at her rather than at Preston. "He had a go at me by having a go at you," she declared.
