Liza Minnelli had her own private screening of “La La Land” before the Golden Globes at the Beverly Hills Four Seasons, Page Six has exclusively learned.

The Oscar winner even gave director Damien Chazelle a precious ’50s musical memento from her late father’s collection.

Sources said the special screening was set up for Minnelli at the hotel’s new 38-seat private screening room, and she saw it with just her close pal and collaborator, singer Michael Feinstein.

Legendary Liza arrived in a Halston outfit with a jaunty black cap, and she loved the film so much she and Feinstein together gave Chazelle an original recording of “An American in Paris” from her director father Vincente Minnelli’s archives.

“I had to pinch myself,” Chazelle told us at the annual BAFTA Tea Party of meeting Minnelli. “She was this joyous ball of energy . . . She got all the film’s references.”

He said the gift was a “pre-record” from the 1951 musical starring Gene Kelly, “before vocals, before anything . . . Her father kept them all. It’s this giant record.”

Chazelle did not watch the film with Minnelli, meeting her after instead.

The film’s also gotten the stamp of approval from Kelly’s widow, Patricia Ward Kelly.

Also at the BAFTA Tea Party, Ryan Gosling and Emma Stone turned into fans themselves when they met the kid cast of “Stranger Things.”

“Game of Thrones” star Sophie Turner walked the red carpet while her rumored beau Joe Jonas sneaked in a back way.

Other guests included Justin Timberlake, Michelle Williams, Harvey Weinstein and Amy Adams.
