Viewers have been shocked this summer by scenes including Chloe Khan pole dancing topless, steamy shower scenes, sexy noises from behind the toilet door, Marnie flashing her boobs, Chloe giving Bear a VERY racy massage and Lewis walking around naked.
Richard's friend and former EastEnders star Ricky Norwood is one of this year's housemates but not involved in any of the controversy.
Speaking on ITV's Loose Women, Richard said: "My mum used to say you're young for a short time and old for a long time so you need to look back and not regret anything.
"I'm watching Big Brother now and I feel for Ricky. He's looking at them thinking, 'In five years' time you will look back and wonder why nobody wants to book you for anything.' You know what it's like, when you're famous and all of a sudden not famous, that's tough."
Richard went on to say: "I'm embarrassed. TV won't stop them because it's good for ratings so they'll let them continue to make a fool of themselves... Why would you do that to yourself?"
