The two also discussed Jason reuniting with his daughter in Australia after two years of not seeing each other due to harsh lockdown rules in the country.
After that, the two began discussing what he does in his free time - which is when Lorraine made the controversial comment, as reported by the Manchester Evening News.
She said: "During Covid, a lot of people have been taking up different hobbies.
"You've been painting but we share the joy of swimming, wild water swimming, isn't it great?
"It actually makes you feel alive."
Jason responded: "It feels fantastic, it gets rid of a hangover."
As a clip of Lorraine swimming was shown on-screen, she burst out: "Oh gosh, there's me and Angus look! There's my wee dog."
Jason then asked: "Lorraine, I didn't realise that I was actually going to see pictures of you swimming, which is fantastic!
"What month of the year was that?"
"That was last month," she replied. "I did do it last November in Scotland though."
"And how was that?" Jason asked - and her response surprised viewers.
"B*****king! It was really cold," she said.
And viewers quickly took to social media.
"Did @reallorraine just swear on #Lorraine when Jason Donovan asked how swimming in November went .. "Bol***king" .. I swear I heard her say .. Or do I need to get my ears syringed. Always a Joy Lorraine," tweeted one.
Another stunned fan asked: "Did @reallorraine just say bol***king?? #lorraine."
"I think @reallorraine might be in for a bit of a bol***king after that #lorraine," a third said.
