Finneas O’Connell, known widely for his music as FINNEAS and for being Billie Eilish’s brother and collaborator, has sealed a major chapter in his personal life. At 28, the singer and producer proposed to his longtime partner, Claudia Sulewski, after seven years of being together.
The couple revealed the big news on Wednesday, September 24, 2025, confirming that the proposal had taken place two days earlier, on Monday, September 22. Their announcement came with a romantic caption on Instagram that read, “forever and ever 9.22,” alongside a series of pictures and a video.
The post showed a sunset setting where Finneas popped the question, while another clip captured them flying in a helicopter to the proposal spot. Sulewski also flaunted her elegant cushion-cut diamond engagement ring in some of the shots, adding extra sparkle to the occasion.
The news of their engagement did not come as a surprise to many who have followed their journey. The two have shared much of their relationship publicly, often blending personal affection with creative projects. Their bond has continued to inspire music, visuals, and shared milestones, making this latest chapter feel like a natural continuation of a love story that started in 2018.
How They First Met
Finneas and Claudia’s love story began in 2018 when they connected through a dating app. What seemed like a simple match grew quickly into something deeper. Finneas wasted no time showing how much her presence moved him.
On the same night they met, he wrote and recorded a song titled “Claudia” and even sent her pieces of it that evening. The track carried lines that made it clear he was already picturing a long-term future with her.
It has been evident over the years that Claudia has been more than just a partner to Finneas; she has also been a muse. In 2022, she played a central role in the song “Mona Lisa, Mona Lisa,” which he dedicated to her.
Not only did she star in the video, but she also directed it. The short film-style music video, which captured their time in Paris filled with affection and closeness, showed the playful and deep side of their relationship. Claudia herself described it as a “gushy video,” reflecting just how much of their genuine love made it into the art.
Public Declarations of Love
Throughout their years together, Finneas has not shied away from showing admiration for Claudia in public. On their fourth anniversary in 2022, he penned a heartfelt message, describing her as a one-of-a-kind woman whose talent, kindness, humor, beauty, and thoughtfulness could not be matched. He went on to call their bond “the impossibility of you,” a phrase that struck many as a poetic expression of his devotion.
The following year, in 2023, he celebrated their fifth anniversary with an enthusiastic post that read, “Happy anniversary to my absolute dream girl!!! Best 5 years of my life!!!” Claudia equally shared her joy, calling him the love of her life and celebrating half a decade of being together with touching photos and words of appreciation.
Even before their engagement, Finneas and Claudia had already built a home and life as a couple. In 2019, they announced that they had purchased their first house together, a milestone that symbolized their seriousness about the relationship. Shortly after that, they adopted a pit bull named Peaches, who quickly became part of their family.
Their shared journey extended to the public eye as well. They appeared side by side at high-profile events such as the Grammys, the Vanity Fair Oscars afterparty, and the Barbie premiere.
Claudia has also supported Billie Eilish and Finneas on several occasions, especially when the siblings released the award-winning song “What Was I Made For?” for the Barbie movie soundtrack. Her relationship with Billie has been described as warm and supportive, strengthening the ties between their families.
Why This Engagement Feels Right
The couple’s announcement has been met with excitement from admirers who have watched them grow both individually and as partners. Their story has not just been about romance but also about building a partnership grounded in creativity, respect, and mutual admiration.
For seven years, they have shared not only love but also creative projects, personal milestones, and everyday life experiences. The proposal is another step in a relationship that has consistently shown stability and growth.
With their engagement now official, attention naturally moves to what comes next. While they have not revealed wedding plans yet, it is clear that their bond is strong enough to handle the spotlight while keeping their relationship grounded. Their engagement is more than just an announcement; it reflects a journey that has already been filled with music, shared dreams, and family moments.
For Finneas, who has seen success as a Grammy-winning producer and songwriter, and for Claudia, who has thrived as an actress, content creator, and entrepreneur, their love story adds a personal triumph to their professional achievements. Their ability to balance public life with private devotion has made their relationship admirable to many.
