Gatsby saved tipsy in the Hamptons.

The “Great Gatsby” star Leonardo DiCaprio was spotted playing good Samaritan over the holiday weekend in the Hamptons when he helped out an inebriated guest at a bash thrown by his longtime pal, hospitality guru Richie Akiva, on Saturday night.

“At one point Leo picked up a very drunk guy, and put him by a pole. The guy was literally falling over,” said a spy at the party at fintech mogul David Rosenberg’s Bridgehampton estate.

“Leo put out his hand on [the pole] so he wouldn’t fall and said, ‘Stay there.’”

Meanwhile, the star’s girlfriend, Vittoria Ceretti, is in Italy for a Dolce and Gabbana campaign.We’re told the guy obeyed the star, and “stayed holding onto the pole.”

DiCaprio, 49, was at the bash with his BFF Tobey Maguire, while his girlfriend, model Vittoria Ceretti, 26, is in Capri, Italy, shooting a steamy ad campaign for Dolce and Gabbana with actor Theo James.

“All the girls were surrounding Leo,” said a spy at the Hamptons party.

A source tells us DiCaprio and Ceretti are still together. They were last seen together in May at a Rolling Stones concert.

Rapper ASAP Ferg performed at the Hamptons estate party, where guests also included Twitter founder Jack Dorsey, NBA star James Harden, Kris Jenner’s beau Corey Gamble and newly single Sports Illustrated model Brooks Nader.

On Friday, DiCaprio, Maguire and Akiva were also spotted at a party hosted by Ambra Battilana Gutierrez — one of the women who brought down disgraced movie mogul Harvey Weinstein — and her pal Lizzy Aiello at Scott Weissman’s home in East Hampton.

Weissman is CEO of lifestyle brand Grey/Ven, which launched a flagship store in East Hampton in May.

“It was a huge house party in the basement with $30,000 to $50,000 paintings on the walls,” said a spy.

We hear Gutierrez DJ’d the party in front of guests including Montana Tucker, artist Shawn Kolodny, comedian Andrew Schulz and model Kelsey Merritt.

The indefatigable DiCaprio also attended Michael Rubin’s starry Fourth of July bash with guests such as Jay-Z, Beyoncé, Tom Brady, Drake, Kim Kardashian and Kendall Jenner.

Maguire was also there, and was photographed exiting the party with 20-year-old model, Lily Chee. (The “Spider-Man” star’s ex wife, celeb jeweler Jennifer Meyer, responded to online trolls, saying, “He was kindly helping a friend to her car, being a good guy.”)

DiCaprio tends to make his way out to the Hamptons annually for Independence Day. Last year the star and his pals rented a historic $28.9 million, 21,000-square-foot spread in Sagaponack Village, we reported.
