With a new season of Bridgerton comes a new host of side storylines to the overarching romantic plot of our series leads. This time round, Luke Newton and Nicola Coughlan are leading the third season as friends-to-lovers Colin and Penelope.


Having been characters we've come to know across the previous seasons, Colin and Penelope's story is a bit of a slow burn as we come to see the pair confront their feelings for one another.

Part of the titular Bridgerton family, Colin's siblings and family dynamics are well-known to many fans of the series but the Featherington clan are full of their own drama, scandals and humour. Penelope's older sister, Phillippa, gets a little more screen time this season and naturally, people are starting to wonder more about the actress who plays her – Harriet Cains.

So, who is she and where may you have seen her before? Read on for everything you need to know about Cains.

Cains has been part of the Bridgerton cast since its debut in 2020 and stars as Philippa Featherington, one of Penelope's meaner sisters who doesn't quite understand her younger sibling.

In the new season, Philippa is married to Albion Finch, played by Lorn Macdonald. She has been tasked by her mother Portia (Polly Walker) to produce a Featherington heir and the final episode of season 3 part 1 sees her and her sister Prudence (Bessie Carter) both believe they are pregnant.

Speaking about her role this season, Cains told Country & Town Home that this season has been "so much fun".

"I absolutely adore her, she doesn’t take life too seriously and she always lightens the mood. It’s so interesting to play someone who doesn’t think before she speaks. Usually there’s a subtext to play with but not with Philly," she said.

Talking more about how she'd describe her Bridgerton character, Cains said: "A lovable dumbass. She’s not book smart but I feel like she’s emotionally smart and that’s something she’s starting to embrace as the season progresses.

"She’s also funny! There’s a theory that she’s a bit of a Paris Hilton in that she has just been playing dumb all this time."

She has recently been posting about the Bridgerton press tour with snaps of herself on the red carpet for the premiere, as well as at other events.
