Sabrina Bartlett, known for her role as Siena Russo in Netflix’s Bridgerton, has revealed her engagement to Australian businessman Lachie Stewart. The 33-year-old actress subtly shared the news through a photograph on social media, taken during a black-tie event in Perth, Australia. The image, showing her alongside Stewart on a luxurious terrace, featured a diamond ring on her engagement finger with the playful caption “Lach’d in” followed by a ring emoji.

A second snap posted by Bartlett showed the couple enjoying a glass of champagne, with the actress humourously holding up her hand to display the ring. Fellow Bridgerton cast member Jessica Madsen congratulated her warmly, commenting: “Ahhhhhhhhhhhh amazing, huge congrats my love.” The engagement ring also made an appearance last week when the couple attended the premiere of David Attenborough’s new environmental film Ocean.
Prior to her relationship with Stewart, Bartlett was in a long-term partnership with actor Tom Greaves. The pair lived together in a flat in East London before parting ways in 2021 after three years. Following the split, she reportedly moved back in with her parents at their seaside home in Kent. At the time, sources said the couple had been “very much in love” but ultimately grew apart, noting their ten-year age gap as a possible factor.

Bartlett’s portrayal of Siena in Bridgerton was central to a key storyline in the first series, involving a passionate but ill-fated romance with Viscount Anthony Bridgerton, played by Jonathan Bailey. Despite Anthony’s eventual declaration of love, Siena moved on, claiming it was too late to reignite their affair. Bartlett had previously gained recognition for her role as Mariette Larkin in ITV’s reboot of The Darling Buds of May, a role that originally launched Catherine Zeta-Jones to fame.
