The Stowaway actress, 50, announced her breakup from Dave Galafassi, 44, on Instagram Wednesday.
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.”
They added that their children — 14-year-old daughter Sage Florence and 11-year-old son Arlo Robert — are their priorities.
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.
Collette and Galfassi tied the knot in a Buddhist ceremony in 2003.
They welcomed Sage in January of 2008 after announcing her pregnancy the previous summer.
Arlo Robert was then born in Australia in April 2011.
