Actor Timothée Chalamet treated his 19.3 million Instagram followers to a bizarre 14-minute live stream on Monday afternoon, during which he smashed a guitar and danced shirtless, reports UNN citing the Daily Mail.

The Oscar-nominated star, who turns 29 this Friday, began the live stream "grimly," sitting in an office chair inside a massive empty soundstage.

Timothée watched a montage of Bob Dylan footage while his 1991 song Blind Willie McTell played in the background.

Chalamet, who portrays Dylan in the film A Complete Unknown, shattered the guitar in a Nirvana-style without uttering a word.

The star of the action film "Dune: Part 2" then raised his arms ceremoniously as the 2009 song I Gotta Feeling by The Black Eyed Peas began to play.

"Welcome, Timothée," flashed on a large screen, misspelling his name.

The screen also lit up with: "You did it. Well done, Timmy. Good luck in the future. Impressive, to say the least. We are so proud of you. We will be watching your other films."

Chalamet danced in front of a ghostly figure resembling his famous girlfriend - producer and star of the Kardashian series Kylie Jenner - who entered the frame, embraced him, and then exited.

Four more people hugged the New York native, who took off his hoodie to reveal a white tank top, dancing throughout the vast space of the venue.

Timothée shot three confetti cannons into the air before deciding to dunk his entire head under a faucet in the sink within the same space.

Then Chalamet removed his tank top. The brand ambassador for Bleu de Chanel dropped to the ground, performed a Homer Simpson-style spin, and thrust his hips several times.

The live stream concluded with Timothée - still shirtless - stepping out onto a rain-soaked loading dock beside the train tracks, humming to himself.

Chalamet's video came after he celebrated Christmas earlier with 27-year-old Kylie Cosmetics founder Kylie Jenner and her 6-year-old daughter Stormi Webster and 2-year-old son Aire Webster, from her five-year relationship with controversial Astroworld founder Travis Scott.

"They had a lovely dinner with Kylie's family, and they went to see the Christmas lights," a source told Page Six.
