And it appears the date holds profound significance for the lovebirds. Exactly three years earlier on that very day, Finneas, 28, had penned an anniversary post reflecting on his relationship with the YouTuber up to that juncture. “You’d have to scour the globe to try to find someone equally as talented, creative, and hardworking as you are, my love,” he wrote on Instagram in September 2022. “Then you’d have to embark on that search a second time to try to find someone as kind, thoughtful, and generous.” But the Grammy winner (whose full name is Finneas O'Connell) didn't stop there. “A third time to find someone as funny, a fourth to find someone as loving, a fifth to find someone as beautiful,” he continued. “How you manage to embody all these qualities simultaneously will forever be the enigma that is you.”

The romantic declaration seemed to strike an emotional chord with Claudia, who responded to the love letter with a poignant remark: “Your vows are going to destroy me.”
