Sensitive star Michael has kept the rest of the house awake at night with his sleep-induced roaring but took exception to gay rugby player Gareth, who likened his heavy breathing to a pig's snort.
Michael said: "You kept saying it over and over, calling me a pig. That's what made me mad. And that was being a bully, man. You're a bully."
A surprised Gareth laughed off Michael's accusations, saying: "I like your style, in fact I love your style."
The poor sports star was probably too exhausted to face an argument after being kept awake all night by Michael's snorting - sorry, snoring!
Despite Gareth not taking Free Willy star Michael's claims seriously, the accusations caused controversy with other celebs.
Loose Women panelist Denise Welch, said: "If there's a bully in here that's bullying someone else then I won't stay. I'd have to go. There's nothing worse in the world."
Will we see a celeb walk over Snoregate?
