When Cass met Karl, she was working as a radio host before deciding to stay home with her children Jackson, 19, Ava, 13 and River, 11 while Karl took on hosting the Today Show on channel Nine.
Karl and Cass announced their separation in 2016. Karl went on to meet Mara & Mine shoe designer and former model Jasmine Yarbrough, 35, and the pair were married in Los Cabos in December 2018.
On her role on Dancing With The Star, the single mum-of-three said, 'There's the Cass that people think of as the former Mrs Stefanovic. I was never a Mrs Stefanovic. I have always been Cass Thorburn'.
She added that her role on Dancing with the Stars will give her the opportunity to be herself.
'It is a fresh start to a new year and a great outlook... I can control being able to present myself as me,' she said.
Cass’s partner on Dancing with The Stars is Marco De Angelis, 24, who she was spotted getting very flirty with in January this year. See the pics here.
Most recently, Marco starred in Burn The Floor, a show dubbed the "world's toughest dance company", but finished up with the company at the beginning of January.
