Bridgerton fans were stunned on Friday morning as they tuned into season two of the period drama and heard Nicola Coughlan speaking with her natural accent.
Nicola, 35, plays the role of Penelope Featherington in the hit Netflix series - but is also well known for her part in much-loved Channel 4 sitcom Derry Girls.
Bridgerton Season one saw actress Nicola speak with a posh London accent as Penelope, who is the youngest daughter of a nouveau-riche family in Regency-era London.
