Leonardo DiCaprio and Tobey Maguire rep their ‘Wolf Pack’ with matching necklaces

Long live the “Wolf Pack.”

Leonardo DiCaprio and Tobey Maguire have been best friends for decades — and they have the bling to prove it.

The two actors were seen arriving together at Hotel Plaza Athénée in Paris on Wednesday wearing matching wolf necklaces.

Stranger still, the BFFs wore practically the same outfit: black Los Angeles Dodgers baseball caps with lightweight nylon navy jackets and black shirts.

Other members of the so-called “Wolf Pack” besides DiCaprio, 48, and Maguire, 47, include Lukas Haas, Kevin Connolly, Vincent Lareska and Richie Akiva.

Founded in the ’90s, the crew was previously known as the “Pussy Posse,” as revealed in an infamous 1998 New York magazine article by Nancy Jo Sales.

But according to the New York Daily News, they renamed the group after DiCaprio’s Best Actor win at the 2016 Oscars.

“The crew was literally howling like wolves all night. They kept chanting, ‘Wolf Pack, Wolf Pack, Wolf Pack!’” a partygoer told the outlet at the time.

DiCaprio and Maguire are apparently in Paris for an event with LeBron James, who may or may not be a member of the pack himself.

Earlier this month, the “Wolf of Wall Street” actor enjoyed a European vacation with his family — including his dad and stepmom, whom he took to a swanky restaurant in London just moments before recent flame Gigi Hadid showed up at the same place.

He later took his parents and his niece to Italy, where he was spotted shirtless on a yacht wearing the same wolf necklace.

It’s unclear when exactly the star and his pals cemented their friendship with the matching jewelry, or whether other members have their own BFF bling.

But one thing’s for sure: the “Wolf Pack” will be on the prowl in Paris tonight.
