Toni Collette and her husband are going their separate ways after 20 years of marriage.

The Stowaway actress, 50, announced her breakup from Dave Galafassi, 44, on Instagram Wednesday, less than a week after returning to the platform.

Collette shared a statement on behalf of both her and her estranged husband, which read, “It is with grace and gratitude that we announce we are divorcing.”

“We’re united in our decision and part with continuing respect and care for each other,” the statement, which she shared alongside a photo of a floral arrangement that reads “PEACE & LOVE,” continued.

They added that their children — 14-year-old daughter Sage Florence and 11-year-old son Arlo Robert — are their priorities.

“Our kids are of paramount importance to us and we will continue to thrive as a family, albeit a different shape.”

Ending with a note of gratitude, they wrote, “We’re thankful for the space and love you grant us as we evolve and move through this transition peacefully. Big thanks.”

Before the announcement post, Collette shared a quote on her Instagram Story that read, “No matter what your current circumstances are, if you can imagine something better for yourself, you can create it.”

Collette’s message comes as photos of Galafassi and another woman kissing at a beach the day before in Sydney, Australia, surfaced. The Daily Mail published the photos that also show the musician and the woman sitting together, holding hands in the water, and sharing multiple kisses.

Arlo Robert was then born in Australia in April 2011.
