The Dancing On Ice star told The Sun that although she is in a happy relationship, she understands how so many former contestants have ended up having romantic liaisons with their professional partners.
Madeley said: "With me and [skater] Michael it's different because he's married and I just started a new relationship.
"It's hard because you're so physical. You spend every day together and I can see how it kind of unfolds very naturally."
She added that she found it difficult to ask Christopher Dean and Jayne Torvill if they had ever had an affair.
"I nearly said to them, 'You really never have...' But then I thought, 'Really unprofessional, Chloe, don't say that'," she explained.
"You've got to respect T & D, but it is bizarre."
