The couple got engaged last year before the birth of their first child, daughter, Arna. Writing on Instagram, the couple said that they "have come to the difficult decision to separate as a couple. We will always be family, and remain good friends and devoted parents to Arna".
The SWEAT co-founders, who grew up together in Adelaide, assured their followers that they will continue to co-parent and run SWEAT as a business together.
"Sharing a lifetime of experiences and special memories from moving into our first apartment and starting SWEAT from our lounge room to becoming parents to our beautiful daughter. Our friendship remains strong as we parent Arna together and run SWEAT as business partners."
We hope that Kayla and Toby have the time and space to heal.
