Poppy Delevingne bonds with her toyboy boyfriend’s sister Princess Olympia

EDEN CONFIDENTIAL: Poppy Delevingne bonds with her toyboy friend’s sister, Princess Olympia, as they pose in matching bikini tops and jeans

Poppy Delevingne has found a classy way to bond with her boyfriend’s family.

The model and actress, 37, has been enjoying a blossoming romance with Prince Constantine Alexios of Greece, 24, since the breakup of her eight-year marriage to businessman James Cook.

She shared this photo of her with his sister Princess Olympia, 26, in which they strike the same pose in skimpy bikini top and ‘Daisy Duke’ cut off jeans.

‘Mirror, mirror,’ jokes Poppy, model Cara’s sister.

I announced in February that Poppy was dating Alexios, one of Europe’s most eligible royal bachelors.

At the time, the model – who is still married to her businessman James Cook of eight years – was spotted with Constantine on a joint walk in West London, near where she lives.

Their public display of affection didn’t stop there, as one eyewitness told me: “They were kissing and embracing in the middle of a bookshop – they certainly weren’t concerned about being seen together.”

Despite the 12-year age difference between Poppy and Constantine – known to his friends as Tino – it is believed that they have been enjoying each other’s company for some time.

Rumors began circulating about the state of Poppy’s marriage since 43-year-old James resigned in January as director of her company, Poppy Delevingne Limited, the company that accounts for her “photography activities.”

Celebrity dating app Raya had added a new account in November with photos that appeared to be of James, but he never confirmed whether it was his account or if someone had opened a parody account instead.

Poppy and James, who works for his family’s aerospace company, tied the knot in 2014 at a church ceremony in Knightsbridge, with sisters top model Cara and Chloe among her many bridesmaids.

Poppy and James would have canceled time for their union at the beginning of last year.

Meanwhile, Tino, son of Crown Prince and Princess Pavlos, is often regarded as one of Europe’s most eligible royal bachelors.

He is the grandson of the late King Constantine II of Greece, who was a cousin of King Charles and one of Prince William’s five godparents. He passed away last month at the age of 82.

Delevingne representatives could not be reached for comment.
