The singer, 22, was joined by her brother and collaborator Finneas at the event, with the pair winning the Chairman’s Award for their hit What Was I Made For? in the Barbie movie.

Eilish carried a black Playboy backpack while posing for photographers on the red carpet at the starry event.

She modeled a luxurious black puffer jacket worn over a white button-up shirt and skinny black tie.

Eilish — who had one of the year’s top songs — strolled into the venue in cropped black pants and shiny Gucci loafers with white crew socks.

Eilish completed her quirky outfit by throwing on a pair of Y2K-inspired sunglasses with a yellow tint.

Her brother Finneas, born Finneas Baird O’Connell, suited up for the occasion in a stylish black velvet jacket and trousers.

He accessorized with a small black bow tie and black frame shades that sat on the end of his nose.

The duo hit the red carpet with the likes of fellow Golden Globe nominees Margot Robbie, Lily Gladstone and Emma Stone.

Billie and Finneas collaborated on the hit track What Was I Made For? which has earned them a Best Original Song nomination.

The song has received high praise from fans and critics and was recently named the Best Song of 2023 by Variety.

It topped the magazine’s list, with boygenius’ Not Strong Enough and Drake’s First Person Shooter coming in second and third respectively.

The outlet described the ballad as ‘the best movie theme since their own No Time to Die,’ which was penned for 2021’s James Bond film of the same name.

Elsewhere in the description, the tune was lauded for its witty, double-meaning lyricism and stripped down delivery.

The haunting number debuted this past July and was accompanied by a music video that saw Eilish transform into a platinum blonde doll-like figure.

In an Apple Music interview with Zane Lowe, the songstress revealed she and her brother were in a stagnant creative state when they were approached about contributing to the Barbie soundtrack last December.

Billie noted she thought collaborating on a song for the album was unlikely, because it had taken months to write the Academy Award-winning No Time To Die.

Director Greta Gerwig invited the songwriting siblings to watch a rough cut of the movie, which starred Margot Robbie as the titular character and Ryan Gosling as Ken.

‘I went into it not thinking that anything would necessarily come of it. I was like, ‘I just want to see this movie. This is so cool. I’m honored to even be thought of,” she recalled.

Billie said Gerwig and screenwriter Noah Baumbach stopped the viewing several times to explain the context of the scenes.

‘She was literally like, “I don’t care. Please just, if you’re inspired, make something. And if you’re not, that’s fine. It’s fine. It would be my dream,”‘ the pop star shared.

She added, ‘Finneas started playing piano, and… those first couple lyrics: “I used to float, now I just fall down,’ just came right out…’I used to know, but I’m not sure now what I was made for.”‘

The superstar also revealed that she ‘did not think about myself once in the writing process.’

However, as she reflected on the finished product, she realized, ‘I’m writing for myself and I don’t even know it. It is one of the most incredible things I get to experience in my life.’

‘It was truly the trippiest thing I’ve ever experienced in my life,’ Eilish reiterated.

Not content to co-write the lyrics and star in the video, Billie also decided she wanted to direct it.

‘I feel really proud of it,’ she said of her directorial debut. ‘It was literally just an image. It was just me turned to the 45 degree angle, left profile, blonde Barbie wig, yellow dress, kind of sage green background, desk.

‘Doing something on the desk, don’t know what it is, that’s all I see. And that was the idea.’
