Timothée Chalamet went on The Late Show with Stephen Colbert on Thursday to promote his new movie A Complete Unknown, but he wound up being confronted over his mustache and goatee.

‘The first time I was on here, I hadn’t hit puberty,’ the 28-year-old Oscar nominee joked to the 60-year-old host.

‘So my voice has changed, and now I’ll probably play The Rock in my next movie.’

Timothée sprouted the sparse facial hair in order to play the titular role in Josh Safdie’s solo feature directorial debut Marty Supreme, which he’s also producing.

But Chalamet must love his new ‘stache considering he could’ve shaved it off a week ago when production wrapped on A24’s $70M-budget ping pong drama also starring Gwyneth Paltrow, Tyler the Creator, and Fran Drescher.

Thursday marked the Dune: Part Two action star’s fourth time appearing on the CBS talk show after previously stopping by in 2018, 2021, and February of this year.

Backstage, Timothée demonstrated a few karate kicks while a mustard-colored sweater was wrapped around his neck like a scarf.

Chalamet arrived at the Ed Sullivan Theater in Midtown Manhattan with two staffers by his side.

The native New Yorker – who styles himself – also wore a blue-suede jacket over a white shirt covered in writing, b&w-striped chef-style trousers, and black lace-up shoes.

Despite it clearly being night-time, Timothée rocked dark sunglasses outside the venue.

Backstage, Chalamet got to mingle with the likes of fellow guest Sabrina Carpenter, who was promoting her Netflix holiday special A Nonsense Christmas.

The Bleu de Chanel brand ambassador transformed into the legendary Bob Dylan for Searchlight Pictures’ fully-authorized biopic, which hits US theaters December 25 and UK theaters January 17.

Timothée reportedly enlisted the same exact team – movement coach Polly Bennett, vocal coach Scott Flaherty, and dialect coach Erik Singer – that his Dune co-star Austin Butler hired to play Elvis in 2022.

On Monday, Chalamet was nominated for the best actor in a motion picture (drama) trophy at the 82nd Golden Globe Awards, which air January 5 on CBS/Paramount+.

The Wonka triple-threat faces heavy competition against Conclave’s Ralph Fiennes, Queer’s Daniel Craig, Sing Sing’s Colman Domingo, The Apprentice’s Sebastian Stan, and The Brutalist’s Adrien Brody.

Timothée has already scored prizes for his performance at Gotham Awards, Boston Society of Film Critics, Astra Film Awards, Palm Springs Film Festival, and Santa Barbara Film Festival.

Two-time Oscar winner Cate Blanchett previously nailed young electric-era Dylan aka Jude Quinn in Todd Haynes’ critically-acclaimed 2007 experimental drama, I’m Not There.

However, A Complete Unknown was executive produced by the enigmatic 83-year-old himself, who tweeted on December 4 that he’s ‘sure [Chalamet is] going to be completely believable as me’ hinting he never intends to watch the movie.

Bob seemed more excited about Elijah Wald’s ‘fantastic’ 2015 book Dylan Goes Electric! the movie was based on: ‘After you’ve seen the movie read the book.’

Director James Mangold’s critically-acclaimed adaptation also features Elle Fanning, Edward Norton, Boyd Holbrook Monica Barbaro, Nick Offerman, Dan Fogler, and Joe Tippett.
