Relationship Status: UnknownThere were reports that Luke is dating his Bridgerton costar Harriet Cains (she plays Philippa Featherington), but honestly? It was mostly based on cute photos, and fans currently think she's dating actor Perry Fitzpatrick, soooo. Either way, Luke likes to keep things private, and said back in 2023 "The more you give chunks of yourself out, the more you sort of colour how you're perceived."
