A source told MailOnline that Poppy is not ready to date yet but that she and Caspar did seem flirty regardless.’

At recent events Poppy has been pictured without her unique blue diamond engagement and wedding rings. 

The stunner married James in 2014 at a lavish Knightsbridge church ceremony, with sisters Cara and Chloe Delevingne among her 17 bridesmaids.   

After being together for five years, James, who works for his family’s aerospace company, proposed in October 2012 with a bespoke jewellery box by Anya Hindmarch.

It contained an engagement ring alongside pictures of the couple and the words ‘will you marry me?’ embossed in gold.

Poppy recently posted about her week at Chiva-Som in Thailand, a health resort whose clients include Elle Macpherson, Naomi Campbell and Kylie Minogue. 

Tellingly, she appeared to be enjoying the solo tip while James celebrated his 43rd birthday back home.

‘If you’re searching for peace, a sanctuary where you can really stop & just BE, if you want to come home feeling like the BEST version of yourself (basically brand spanking new or a little like Beyoncé must feel most days) then Chiva Som is for you,’ she wrote on Instagram.

The Mail On Sunday reported last month that before the transformative Thailand trip, Poppy moved into her own place in West London, with an insider spilling: ‘James is refusing to accept things are over.’ 

Speaking to The Times last month Poppy didn’t mention James, instead focusing on her close relationship with older sister Chloe, 35, and younger sibling Cara, 29.  

‘When my sisters and I get together it’s hard for anybody else to keep up, we’re very loud, finish each other’s sentences and it can get quite intense,’ she admitted, before revealing that she had moved in with her older sister Chloe and her family during the 2020 lockdown.   

Split? Last month the Mail On Sunday reported that Poppy and her husband James Cook ‘have consciously uncoupled’ and have been little more than friends for the best part of a year (pictured in a 2020 Instagram photo)
