'We hadn't met before, we just went into the studio and talked about music,' Ronson said of Gosling. This week, soundtrack producer Mark Ronson also revealed while speaking to Variety at the Los Angeles premiere of 'Barbie' on July 9 that Guns N' Roses guitarist Slash is on Gosling's 'I'm Just Ken' song. I cannot wait for you to hear what we've created together 💪🏻 👅.' The song will be released alongside the film on July 21.

I was invited by the incredible and Greta Gerwig to write a song from the perspective of Ken for one of the scenes and we honestly had so much fun with this.

Wrote Smith, 'I cannot begin to express how incredibly excited I am to be a part of the soundtrack to this already iconic film.

Their track is titled 'Man I Am,' and is from the perspective of Ken, Smith said on Instagram. On July 10, the final special celebrity artist on the soundtrack was revealed to be Sam Smith. In it, Eilish - wearing a yellow dress and sporting a Barbie ponytail - pulls doll-size versions of some of her own most iconic outfits and solemnly tries to fit them all on a doll clothing rack, despite wind and then rain. GET READY TO SOB.' She then released the tragic song and video on July 13. THIS MOVIE IS GONNA CHANGE UR LIVES AND HOPEFULLY THE SONG WILL TOO. Then, on July 6, Billie Eilish made the surprise announcement that she has a song on the soundtrack, too, titled, 'What Was I Made For?' She wrote on Instagram, 'WE MADE THIS SONG FOR BARBIE AND IT MEANS THE ABSOLUTE WORRRRLLLD TO ME. The track samples perhaps the most iconic Barbie song: Aqua's 1997 hit, 'Barbie Girl.' And on June 30, Charli XCX released her 'Barbie' track, 'Speed Drive.' On June 23, Minaj and Ice Spice's track, 'Barbie World,' was released alongside fun, Barbie Dreamhouse-set visuals. Then, on June 2, Karol G released her 'Barbie' track, 'WATATI,' featuring Aldo Ranks, and on June 9, PinkPantheress released her contribution to the soundtrack, titled 'Angel.' Her 'Barbie' song, 'Dance the Night,' dropped on May 26 with a vibrant, disco-themed music video. These artists join pop star Dua Lipa (who plays a mermaid Barbie in the movie). When the highly anticipated 'Barbie' movie hits theaters on July 21, fans will also be able to blast 'Barbie: The Album.' On May 25, Atlantic Records announced news of the album, which will be released the same day as the film, also sharing some of the all-star artists who are featured, including Nicki Minaj, Ice Spice, Haim, Lizzo, K-pop group Fifty Fifty, and - perhaps most interestingly - Ryan Gosling, who plays Ken in the movie. The summer of Barbie is getting its own soundtrack.
