A Swedish-born former model has ditched her husband of more than 20 years to marry her identical twin sister's spouse, Page Six reported.
Glamorous Swedish-born Charlotte Bonstrom has left her longtime partner Vittorio Assaf, the co-founder of the high-end New York Serafina Restaurants, for her brother-in-law, according to Page Six.
Charlotte, aged 50, now intends to marry Thierry Gillier, the founder of the fashion label Zadig & Voltaire, and her sister's husband, after starting an affair with him in March 2020, the publication reported.
"Charlotte had an affair with Thierry and it broke Celia's heart," a source told Page Six. "Poor Cecilia, betrayed by her husband and her twin sister."
Assaf confirmed to Page Six that he and Charlotte, who own homes in Manhattan's Upper East Side and the Hamptons together, and have two children together, are getting a divorce. "She wants to get remarried," he added.
He also denied rumors that he had paired up with Cecilia following the news of the divorce. "I have nothing to do with the sister of Charlotte," he told Page Six.
The twin sisters have not appeared on each other's social media feeds since March last year, when the affair is believed to have begun, according to The Sunday Times.
Cecelia appeared to reference the affair in cryptic Instagram posts in March 2020, the paper said.
"You're looking for three things generally, in a person: Intelligence, energy, and integrity," she wrote. "And if they don't have the last one, don't even bother with the first two."
She tagged both her husband and sister in the caption.
