Courteney Cox was left confused after a discussion over the Scouse accent on Saturday's instalment of The John Bishop Show.
Fresh from the current success of the fifth Scream film, the Friends star was on the show to promote her new comedy-horror series called Shining Veil.
She was joined on the sofa by Downton Abbey star Hugh Bonneville.

As the show opened, John discussed living near Hugh during lockdown, and even bumping into him at a vaccine centre.
While telling the anecdote, John put on a "posh Southern accent" to imitate Hugh.
John then asked Hugh if he had a "Scouse accent in his locker", to which he replied: "I'm not Martin Freeman".
Hugh then asked Courteney how her Scouse is.
The former Friends star looked completely bewildered on hearing the word.
She said: ""Scouse? I don't even know what that means."
When Hugh explained it was how John speaks, she had a realisation.
Courteney said: "I know that when I first met you, I needed to see your mouth move at the same time.
"If we were taking a walk and I was behind you it was like uh oh... I didn't understand."
The John Bishop Show airs Saturdays at 9.30pm on ITV and the ITV Hub
