He said programmes like Popstars: The Rivals and Fame Academy are "ruthless" and mess with the contestants' lives for the sake of entertainment.
Robbie said he had nothing against anyone following their dreams, but only if they actually had some chance of success.
"There's a lot of talent but it's such cruel television," he said. Although he did add: "But it's great TV."
He said Popstars: The Rivals was particularly harsh as it made the teenager who's just been booted off the show sing live just seconds after they found out the bad news.
