Paulson dating half his age

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

After Page Six exclusively revealed he is getting a divorce, we have learned that the 65year-old hedge funder is dating 33-year-old dietitian Alina De Almeida (pictured below).

Sources said the new couple met this summer and things have been going so well they are already living together in his swanky Fifth Avenue 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 billion — filed for divorce from his wife of 21 years, Jenny, 50, this week.

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 registered dietitian and expert in weight loss counseling, 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’s and Cornell’s NewYork-Presbyterian medical centers, according to her company’s Web site.

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 hot spot Le Bilboquet.

Page Six revealed that Paulson filed for divorce in Suffolk County Monday. He and Jenny have two daughters — and no prenuptial agreement, according to sources. This sets the stage for an epic divorce battle over his billions and their extensive property profile, which includes estates in Southampton and Aspen, and a 28,000-square-foot apartment in Manhattan. Paulson’s attorney William D. Zabel declined to comment. De Almeida did not get back to us.
