The ex-So Solid Crew member had, after a night of drinking, flashed his behind to several housemates before rubbing himself up against them, actions which landed him with a warning from Big Brother.
Julian Clary later told the rapper: "You did quite a lot of bottom work last night, I don't know if you remember. Slightly alarming."
Martin had earlier said that he thought Harvey had been "disrespectful" to Coleen Nolan, which she dismissed, saying he was "absolutely slaughtered".
Martin argued "That's no excuse", and after being confronted by Harvey, who said he had become aware of "people having a moan up about me". The ex-EastEnders star told him he thought he "crossed the line from respect to disrespect against a woman...You did something that you would do with the boys at football".
Harvey disagreed, but the pair shook on it after Martin reminded him: "We're on the same page."
However, Martin left him with some final words of wisdom: "There's a line between showing someone your arse and your arsehole."
