The award-winning actress may be reaching new heights with her latest role in Netflix hit,
Bridgerton, but if there is one person that keeps her grounded it’s her mum.
The 33-year-old joined Taskmaster for the show’s one-off New Year special, facing off against actor John Hannah, who is most-known for his role in
Four Weddings and a Funeral, journalist Krishnan Guru-Murthy, presenter Rylan Clark-Neal, and
Strictly Come Dancing judge Shirley Ballas.
All was well until Coughlan, who plays Clare Devlin in the Channel 4 comedy,
Derry Girls, dropped the S word.
With her gaffe now forever immortalised in GIF form, the actress took to Twitter to tell fans that she’s still in hot water with her mum.
“My mum was so cross at me for saying shite on TV that I’m still paying the price for being such an edgelord.”
Fans of the star were quick to show their support.
One tweeted: "What are mammys for it not to keep you grounded."
While another wrote: "Never watched taskmaster. Now I have a reason. Shite is not used often enough on TV.”
The Galway girl is currently wowing audiences in 'Bridgerton', where she plays wallflower, Penelope Featherington.
"Penelope is a young girl who is a member of high society but feels very much like an outsider," Coughlan says.
"We see her in her first year debuting, meeting the queen and going to balls; and she feels completely uncomfortable about it. She's a wallflower, she stands at the back and doesn't dance with anyone.
"But she's a fascinating character because she starts off very innocent but goes on this amazing journey in the series which really changes her."
