The Happy Mondays hellraiser has hinted that some might be faking it in the all stars special.
Viewers were captivated to see how he might get on with his old foe, diet guru Gillian McKeith.
Shaun commented: “I’ve bumped into Gillian at least ten times in the last 12 years with her kids, with my kids, and I thought we’re all good.
“But at first Gillian’s head was still stuck 12 years ago, she was ready to battle with me.
“I was working hard at making me and her get on, and as far as I was concerned I got on with everybody and everyone was having a nice time.”
Gillian rocked camp with an elaborate secret plan to smuggle in contraband including mints, almonds and salt.
Shaun said: “At the end of the day… how can I put it? Gillian’s a grafter.
“We all know I think Gillian’s fainting [in 2010’s camp] is a load of b******s.
“The smuggling was typical Gillian.”

He added: “I love Paul Burrell, but the end of the day Paul comes from a pit village. Paul’s dad was a miner, Paul is hard as f***.
“I think Paul’s great, but I did take the p*** out of Paul’s screaming in trials.
“But you know. It’s just a laugh.”
Other celebrities in camp include Janice Dickinson, Carol Vorderman and Phil Tufnell.
Shaun said: “I think Janice Dickinson is f***ing amazing and there was a lot of really cool people in there.
“I mean, Janice is on my level. She’s mad as a bag of bouncing frogs, which is cool by me.
“When I was in there the first time round my biggest fear was people, I have my pals and that’s it, I don’t know a lot of showbiz people or whatever.
“But both times we had a great bunch so I was lucky. There wasn’t any d***s.”
