Sienna Miller is engaged.
The Factory Girl actress and partner Oli Green welcomed their second child earlier in 2026 and now it has been revealed they are getting married.
The 44-year-old star - who also has daughter Marlowe, 13, with former partner Tom Sturridge, and a two-year-old daughter with Green - stepped out in Spain last week sporting a huge diamond ring on her engagement finger and E! News confirmed the sparkler is an engagement ring.
The couple are largely private about their lives, keeping their kids out of the public eye, and it only emerged Miller had given birth to her third child when she let the news slip last month while promoting her latest project, Jack Ryan: Ghost War.
"It's happened. I have a tiny baby next door," she told E! News.
