The Mr Paparazzi creator surprised housemates when he revealed his washboard stomach.
Lyons claimed that he has had a surgical procedure known as 'contouring' to achieve his six-pack.
Andre said in his New magazine column: "I'm fascinated by Darryn Lyons's abs! I can't quite figure out what he's done, to be honest.
"I know he said it was body contouring but I think it looks more like implants."
The 38-year-old continued: "I've never seen anything similar before, but I'm not criticising him - it's just different."
However, Andre praised Lyons for not being shy, writing: "I do like the fact that he's confident about his body."
