Hayes and Cullen originally announced their separation in May, and have officially filed for divorce this week, citing irreconcilable differences.
In the ’90s, Savage Garden, an Australian band consisting of Hayes and Daniel Jones, was known for hits including “Truly Madly Deeply, “I Knew I Loved You,” and “Affirmation,” in which the band stated their support for gay rights in 1999.
Hayes and Cullen, a director and screenwriter, got married in 2005, and then again in 2013 after it was made legal in the United States.
Hayes previously opened up about the split in a since-deleted Instagram post where he talked about how he was usually “an intensely private person when it comes to my home and family life” but wanted to be honest with his fans.
“After 17 years of marriage to the best person I ever met, Richard and I have chosen to accept that our union has greatly and beautifully come to rest,” he wrote, according to The Daily Mail. “In honor of this realization, we separated earlier this year and have been supporting each other emotionally throughout this massive change in our lives.”
“No, there’s no scandal to report, no infidelity, guilty or third party,” he continued. “It’s just life. We adore each other and always will. We view our marriage as our greatest collaboration. Nobody can ever take away what we achieved together. We are still best friends. We always will be.”
