Last night the singer lashed out at Keith Chegwin in a late night row but his fellow celebs admitted it wasn't the first time that he's got drunk and turned rude in the house.
It follows Kavana's infamous drunken rage on ITV2's The Big Reunion last year.
“I got a bit merry and there was a camera crew waiting for me," he recalled recently. “I said come in, let me give you what you want.
“Come on let’s do this.
“If you’re going to make a fool of yourself, do it on national television.”
Speaking before entering the house, Kavana vowed to avoid getting so drunk things turned messy.
“I’m not a nasty drunk, if I do decide to have a few drinks, it will surely be just good fun," he said. “But I’m going to take it easy I imagine.
“The Big Reunion, it gave me a kick up the bum really.
“It was really hard to watch but I had a good response from it and I took it as a positive. "
This week Kav's former 5th Story band member Kenzie said that the CBB housemate was in a better place now compared to his appearances on telly last year.
"I think he's shown the most maturity I've seen from him - and people seem to warming to him," Kenzie told new! magazine. "I think it was just one outburst on the last series of The Big Reunion that gave everyone the impression he's like that and he's actually not."
