The 29-year-old, who is married to Popstars and Dancing On Ice star Jessica Taylor, argued that the competitors on shows such as Big Brother do not deserve fame.
"I hate these reality TV shows where people walk off Big Brother and think they're A-list celebrities when they've done nothing in their lives, it really does my head in," he told Channelbee.
The sportsman also rubbished a long-standing rumour that he enjoys cooking at home naked.
"The most ridiculous thing I've heard about myself is [that I like] cooking naked. I've heard a couple of times that I cook naked at home," he said. "That is ridiculously outrageous and not true at all. I don't cook so how can I cook naked?"
