Poppy Delevingne, 38, dating 'most eligible bachelor' Sienna Miller's ex Archie Keswick, 42
Poppy Delevingne, the sister of model and actress Cara Delevingne, is said to be dating Sienna Miller's ex.
It has been reported that the 38-year-old has enjoyed a number of romantic dates with Archie Keswick who has been described as "the most eligible bachelor you've never heard of".
The 42-year-old Archie is a member of the Jardine Matheson dynasty which owns the Mandarin Oriental Hotel Group. His family fortune is reputed to be more than £6 billion.
A source told the Daily Mail's Eden Confidential column: "It's a serious relationship." The new budding relationship comes after the model Poppy split up with her former boyfriend, Prince Constantine Alexios of Greece and Denmark, 25, last December.
The Greek royal, affectionately known as Tino, is Prince William's godson.
Speaking about the breakdown of her former romance with the royal, the source told the Daily Mail: "They are just at different stages of their life. There is no animosity."
Before that Poppy split from her husband, James Cook, 41, in 2022 after eight years of marriage, although the pair have never publicly addressed the break-up.
Poppy and businessman James enjoyed two wedding ceremonies with a lavish ceremony in St Paul's Church, in Knightsbridge, London and the other in Marrakesh, Morocco.
Poppy's wedding dress was Chanel and she had sister Cara as maid of honour (also in Chanel). Trinny Woodall, Mary Charteris and Charlotte Tilbury were among the celebrity guests.
Despite the couples split, Poppy previously revealed she would save her two wedding gowns from a fire above any other possession she has, even though one dress is now on display in a museum in Norway.
Speaking on This Old Thing? podcast, she said: "I had one [dress] designed by the wondrous Karl Lagerfeld, for Chanel.
"For part two, I wore a Peter Dundas for Pucci wedding dress. That’s now in a museum in Norway - he’s stolen it back from me. I want it back because I want to do the washing up in it.
"[I’d save] those two things if my house is burning down — they hold so much sentimental value."
As both Poppy and Sienna run in celebrity circles, there's no surprise that they have been spotted at the same events. Poppy's sister Cara has also been known to spend time with Sienna in the past at parties with famous faces.
The Daily Mail reported that at the end of April, Poppy and Sienna both attended the 25th birthday party of their aristocrat pal Lady Lola Bute
The daughter of the late John Crichton-Stuart, 7th Marquess of Bute and fashion designer Serena Bute, hosted guests at her family seat Mount Stuart House on the Isle of Bute in the Scottish Highlands.
