Lydia Tár would’ve hated Cate Blanchett’s Glastonbury dance. But the crowd loved it

Lydia Tár probably would have detested Cate Blanchett‘s unexpected performance at this year’s Glastonbury music festival — but the crowd absolutely ate it up.

The “Tár” star made a cameo this weekend at the English event, joining eclectic-pop sibling duo Sparks onstage for a live performance of “The Girl Is Crying in Her Latte.” Her Day-Glo yellow pantsuit and quirky dance moves were a far cry from her Oscar-nominated, no-nonsense portrayal of fictional maestro Lydia Tár.

“We have a super special treat tonight,” singer Russell Mael said Friday during Sparks’ set.

“We did a video for this song recently, and we had the great honor of having the amazing actor Cate Blanchett join us in that video. Without further ado, Cate Blanchett!”

On cue, Blanchett emerged in her vibrant ensemble — complete with green, cat-eye sunglasses and bulky red headphones — before flailing her arms, wiggling her legs and convulsing to the edgy beat. At the end of the number, Blanchett took a deep bow as the audience erupted in cheers and applause.

As mentioned by Mael, the 54-year-old actor previously appeared in the music video for “The Girl Is Crying in Her Latte,” which is basically just three straight minutes of Blanchett dancing while the Mael brothers mill around in the background. The song is the title track of Sparks’ 25th studio album, which came out in May.

Blanchett’s surprise appearance was among several buzzy moments to come out of Glastonbury this weekend.

Singer Lana Del Rey also made headlines after she arrived late for her set, and her performance was cut short. The “Summertime Sadness” hitmaker showed up about 30 minutes late on Saturday, according to the Guardian.

“I was so f— late that I am about to rush this set today,” Del Rey tells the audience in footage from the show.

“If they cut power, they cut power. I’m super f— sorry. My hair takes so long to do. I love you to death. Let’s keep on running the set as its supposed to go.”

The festival didn’t completely turn off the electricity — but it did eventually mute the performer’s microphone to discourage her from staying on past the midnight curfew. Even after her mic stopped working, the “Did You Know That There’s a Tunnel Under Ocean Blvd” artist managed to lead the crowd in an a cappella rendition of her 2012 song “Video Games.”

Glastonbury was scheduled to continue Sunday with Elton John, Lil Nas X, Blondie and other musicians. This year’s lineup also features Lizzo, Arctic Monkeys, Guns N’ Roses and Rick Astley.
