The British actress Sienna Miller is reportedly engaged to her long-term partner, Oli Green, just one month after they welcomed their second child together in May.
The Layer Cake actress, 44, was photographed sporting a glittering diamond on her left hand while out and about in Spain, sparking rumours her beau, 28, had popped the question.

Brett Afshar, jeweller and founder of award-winning jewellers, Queensmith, explains that it's likely Sienna's sparkler, which appears to be set in yellow gold with a classic six-claw setting, is vintage, and is estimated to be worth between £50,000 and £70,000.

Brett added: "Sienna's style leans heavily toward a classic, old-money aesthetic, which aligns beautifully with the ring her partner chose. A round solitaire is one of the most timeless and understated engagement ring styles, embodying elegance without excess. It stands in contrast to the recent celebrity trend of oversized cushion-cut and oval diamonds, making it a sophisticated choice that feels both refined and enduring."
Popped the question
Sienna has been in a string of high-profile relationships and has been proposed to three times.
The Horizon: An American Saga actress was first engaged in 2004, when British heartthrob Jude Law got down on one knee on Christmas Day. The pair met in 2003 while starring in Alfie, but their betrothal was called off in 2005 after the Holiday star had an affair with his children's nanny, leading to a public apology from the Hollywood actor.

Tom popped the question in 2012, but their engagement was called off in 2015 when it was announced that they had split.

In a 2022 interview with DuJour, Sienna opened up about her series of engagements, quipping that "it's better than three divorces."
"I've dealt with very public heartbreak. I was never somebody who dreamt of getting married. I've been engaged a few times, but I've never been married. It's better than three divorces, I think," the actress said.
