Finneas Marries Claudia After Songwriting Sparks | Entertainment and Celebrity News

Finneas O’Connell, Grammy-winning producer and Billie Eilish’s brother, tied the knot with longtime girlfriend Claudia Sulewski in Montecito, California — a love story that began on a dating app in 2018, sparked instantly, and has blossomed through music, art, and now marriage.

Their engagement, announced in September 2025 after a sunset proposal, was preceded by Finneas’ sleepless nerves over perfection — which he finally let go of. Claudia, host, actress, and founder of a skincare line, dazzled in custom Oscar de la Renta looks across the wedding weekend — a celebration of creativity, chemistry, and a love that’s always been written in notes and melodies.
