“I love Nessa because she is nothing like the real me. She is always there at the back of my mind and when channelling my inner Nessa, I can be rude.”
She revealed Nessa – catchphrase Tidy – who has made her a comedy icon, was based on those who had “that sort of ultra-calm, afraid-of nothing, never-get-riled attitude”.
She said: “Plus she has this confidence that makes her attractive. She isn’t bothered by what people think of her and that is refreshing in this day and age when we are obsessed by how we appear on social media.”
But she dashed the hopes of Gavin & Stacey fans that other episodes are planned.
