Finneas O'Connell, the 28-year-old singer-songwriter and producer, best known for his collaborations with his sister Billie Eilish, is engaged to his longtime girlfriend, Claudia Sulewski. The couple, who have been together for seven years, announced their engagement on Wednesday, September 24, 2025, with a series of photos on Instagram. The photos captured the romantic sunset proposal that took place on Monday, September 22, 2025.
The Instagram post featured a carousel of images, including the couple kissing on a hilltop and Sulewski showing off her cushion-cut diamond engagement ring. The caption simply read, "forever and ever 9.22". The proposal involved a helicopter ride to a picturesque hilltop location. Sulewski wore a red dress, while O'Connell sported a black t-shirt for the occasion.
O'Connell and Sulewski met in 2018 on a dating app. According to reports, O'Connell was so smitten with Sulewski after their first meeting that he wrote a song about her that very night, titled "Claudia". The lyrics included the lines, "I think you're gonna change my plans / With those emerald eyes / But you don't even understand / How much they're on my mind". Sulewski has since become an inspiration for O'Connell's music, including his song "Mona Lisa, Mona Lisa," for which she also directed the music video.
Sulewski, 29, is a YouTuber, actress, and host. She began her YouTube channel in 2007, focusing on fashion, beauty, and lifestyle content. She later moved to Los Angeles and began hosting for Teen Vogue's YouTube channel. She has also appeared in acting roles, including the 2022 film "I Love My Dad".
Over the course of their relationship, O'Connell and Sulewski have collaborated on various projects. In 2020, Sulewski was featured in O'Connell's "Mona Lisa, Mona Lisa" music video, which showcased intimate moments between the couple in Paris. They also started a podcast together called "We Bought A House" during the COVID-19 pandemic, but they later stopped feeling like they were "sharing too much".
The engagement announcement has been met with an outpouring of congratulations from fans and fellow artists. Many have expressed their excitement for the couple and admiration for their relationship.
O'Connell has achieved significant success in the music industry, winning 10 Grammy Awards for his work with Billie Eilish. He has also produced music for other artists, including Selena Gomez, Halsey, Justin Bieber, Demi Lovato, and Camila Cabello. Sulewski has built a successful career as a YouTuber and actress, with a substantial following on social media. She also has a beauty line.
The couple bought their first house together in October 2019. Their Los Angeles home includes a recording studio for O'Connell and an office for Sulewski.
