Sulewski has also been a creative collaborator with Finneas, notably directing and starring in the music video for his 2022 hit "Mona Lisa, Mona Lisa." The video, a sweet portrayal of the now-engaged couple sharing intimate moments in Paris, left an indelible mark. "It's a gushy video, for sure!" Sulewski told Vogue at the time. "We're pretty deep in it at this point—we've been dating for almost four years, so I think the cat's out of the bag."
