Billionaire, 65, divorcing wife and now dating Instagram model, 33

A man famous for making $20 billion betting against the housing market before the 2008 crash has a new girlfriend after leaving his wife.

They say age is just a number — but so is billionaire John Paulson’s bank balance.

After the New York Post exclusively revealed the hedge funder is getting a divorce, we have learned the 65-year-old is dating 33-year-old dietitian Alina de Almeida.

Sources said the new couple met this summer and things have been going so well they are already living together in his swanky Fifth Ave apartment in Olympic Tower.

Paulson — who famously made $20 billion betting against the housing market before the 2008 crash and is said to be worth at least $4.7 billion — filed for divorce from his wife of 21 years, Jenny, 50, on Monday.

A source said: “John does have a new, much younger girlfriend and while it is still early days, the relationship is blossoming. They are very happy.”

De Almeida is a certified registered dietitian and expert in weight loss counselling, and runs the company Effective Lifestyle, which also has an Instagram feed featuring her in skimpy workout gear and offering nutrition tips.

The beautiful brunette from Montclair, NJ, completed her residency and clinical nutrition rotations at Columbia and Cornell NY Presbyterian Hospital, according to her website, effective-lifestyle.com.

It is not clear how the new couple met, but sources say they were spotted numerous times together in the Hamptons over the summer, dining at sceney locations like Sag Harbor hotspot Le Bilboquet and East Hampton Japanese eaterie O by Kissake.

On Tuesday, it was revealed Paulson had filed for divorce from his wife Jenny, with whom he has two daughters, in Suffolk County, Long Island.

The couple does not have a pre-nuptial agreement, according to sources, setting the stage for an epic divorce battle over his billions and their extensive property holdings which includes estates in Southampton and Aspen, as well as a 28,000 square-foot apartment in Manhattan.

Both Paulson and Jenny are well known as generous philanthropists, having given $100 million to the Central Park Conservancy, almost $10 million to charter school network Success Academy through the Paulson Family Foundation, plus his donation of $400 million to Harvard to endow the School of Engineering and Applied Sciences.

The Paulson Family Foundation could become a bone of contention in the divorce, because it is extremely important and valuable.

They have both hired top New York divorce lawyers.
