I'm A Celebrity star Beverley Callard once knocked on Charlie Lawson's door - wearing nothing but a thong and a pair of socks.
The Enniskillen-born actor, who played Jim McDonald opposite Beverley as Liz in Coronation Street, said they and other Corrie stars loved to let their hair down off camera.
But the last thing he was expecting that night was Beverley to knock on his door almost stark-naked.
He said: "She did, God bless her, that's right.
"She came into the room and climbed into bed and I said, 'Darling, we're working tomorrow so I'm just going to carry you out and put you back in your own bed.'
"And she was very sweet about it the next day."
Charlie had earlier that same night leapt to the defence of his Corrie co-star after a boozing session they had with another actor who tried to take her to bed.
He said: "He thought it might be amusing to try and pull her.
"He was very drunk, we were in this boozer and he wanted to get her upstairs so I had to have a wee word with him.
"But apart from that he was a very nice chap - he behaved impeccably after that."
In her memoirs, Beverley (63) said the eventful night happened at a pub that did bed and breakfast, called The Commercial, at the back of Granada Studios.
She said: "One night we were both staying there with another actor called Vincenzo who was playing a former army mate of Jim's who'd had an affair with Liz years before.
"Charlie insisted on calling Vincenzo, 'Vincey Baby' and every time he walked in the room he'd say, 'How ya' doin' there Vincey Baby?'
"I'd decided that every time Charlie had a Bushmills whiskey (which was his drink at the time), then I'd have a vodka and bitter lemon. After a while I was off my face.
"Charlie was saying, 'She's been f****** unfaithful to me with Vincey Baby. This is f****** outrageous.' We were all having a hysterical time.
"The more I drank, the more outrageously flirty I became with this Vincey Baby guy. I'm not usually like that but he must have thought, 'Yes, I'm in here.'
"He was coming on to me big style and I was thinking, 'Oh great.' Then this Vincey Baby said to me, 'Shall I take you upstairs?' I lurched round to Charlie and slurred, 'Charlie, I'm just going upstairs with Vincey Baby. I won't shag him, we're just going to cuddle.'
"Charlie was having none of it. 'No you're f****** not,' he said."
Beverley said things then "started getting a bit heated" between the two men, with Charlie warning him: "If she does anything with you she'll be so f****** sorry in the morning. She's married with a wee baby. You can't do this."
But when 'Vincey Baby' then told Charlie it was none of his business, Beverley said it all kicked off.
She said: "Now Charlie was boiling. 'Right, I believe tomorrow we are on set at 7.15 and we've got big scenes together. Do you want to play those f****** scenes with a f****** broken jaw? You are not taking her to bed,' he said.
"At that, Vincey Baby disappeared off, leaving Charlie to pick me up, carry me to my room, plonk me on the bed and leave. I was saying, 'Oh Charlie, don't leave me, don't leave me.'
"But he is a very honourable man and went back to his own room. He'd only just shut the door though when there was this knock, knock, knock on it and a voice calling, 'Char-lie, Char-lie.'
"It was me - wearing nothing but a white thong and white socks.
"He knew I'd regret it in the morning if anything happened, so he took me back to my room again, put me on the bed then laid next to me all night with his arms folded and still wearing his jeans, leather jacket and Timberland boots!
"How rough did I feel the next morning? Oh my God! Looking back I still can't quite believe how outrageous I was that night.
"It was really out of character and like Charlie said, I would have been mortified the next morning if I had gone off with another man."
And on another dramatic night out, Charlie (61) inadvertently set fire to Beverley's famous frizzy hair.
He said: "She was lying over my lap and I was a smoker in those days.
"I was talking to the driver and all of a sudden - you know the way a hair burns - there was a flash of light and a very strong smell of burning hair.
"And I was whacking her head and a whole big lump of hair came out of the back of her head.
"She had already that evening jumped on top of the speaker with Sue Johnson of Royal Family and everything else fame.
"And they'd both been dancing on top of one of the speakers at this gig we were at, I think it was a Brookside party. And they fell off - and all the sound went.
"But in those days we all got together on a regular basis, the Brookie lot and us, and there was a very good camaraderie between us all, I don't know whether there is any time for that anymore."
In her book Unbroken, Beverley called it "another outrageous night" at the boozy bash in Liverpool. She said: "So we got to this party and again, every time Charlie had a Bushmills, I had a vodka and bitter lemon.
"I think I've only been that drunk with Charlie about four times but this was the worst.
"There was this great jazz band playing and for no reason whatsoever I got up on the stage and started doing backing vocals, knocking over a massive speaker in the process.
"In the car on the way home, Charlie was having a cigarette and I was chattering away when suddenly I collapsed on to his knee.
"A couple of minutes later, Roy the driver was saying, 'Charlie, is Beverley all right back there? I can smell burning.' No reply from Charlie. 'Charlie, Charlie, I can smell burning,' said Roy, becoming increasingly anxious.
"What I'd done was fallen asleep onto Charlie's cigarette, which had caught light to my hair. Charlie was frantically banging my head with his hands, trying to stop it smoking, while I was still totally out of it.
"The next morning I was first on set and had to do a scene with Brian Mosley in the corner shop.
"I felt like death. I was halfway through the take and I went to run my hands through my hair when a great big clump just fell out in my fingers.
"I thought, 'Oh my God, I've drunk so much vodka my hair is falling out!' It was only later Charlie told me what had happened.
"We had such a laugh together and despite my daft come-on the night I was paralytic, there never ever was anything romantic between us.
"We were both married for one thing. We were just great mates then and still are to this day."
Charlie added: "We were very close. She put up with a lot from me, you know what I mean?
"I was wild in those days but we worked extremely well together and we never got into trouble.
"Those days it was different, having the craic wasn't frowned upon so much.
"So Philip Middlemiss and I, he played Des Barnes, we certainly had a candle for about a year but then we were burning fresh air.
"We had a good four or five years Philip and I and, of course Bev was there in the thick of it but we all looked after each other.
"I wasn't by no means the only person - everybody was rockin' and rollin', you know, Lynne Perrie for goodness sake, Briggsy (Johnny Briggs, left, who played Mike Baldwin) loved a drink and all that carry on.
"But it wasn't frowned upon if you turned up, and you weren't late - what they couldn't stand was lateness, and I couldn't stand that either because I was never late.
"Some people were late and they had to be told, and I would say, 'Listen, if I can stay up all night and get here at seven o'clock in the morning, I'm f***ing sure you can.'"
