"I love this show and even more when I get to join these fantastic presenters, the kindest and most supportive presenters in the business."
Cass and Karl, who were married for 21 years, split in 2016, and share three children, son Jackson, 20, daughter Ava, 12, and son River, 12.
While she had been a full-time mum for most of her children's lives, Cass recently revealed that she returned to work for the sake of her family.
"My family broke down, and I’ve had to navigate making my way back into the workforce — not because it felt right, but out of financial necessity," she shared.
She explained that her decision to accept certain roles was "as a means to an end".
"When Dancing with the Stars came up, a full- time gig but for three only 3 months, I took it.
"I am sure many single mums could relate to this position. It was a means to an end. I needed a car and I needed to try and change the dialogue that surrounded me," she said.
Cass also opened up about co-parenting with Karl, saying their situation was a "massive challenge" for everyone involved."
Speaking on The Juggling Act podcast, the 48-year-old said “Co-parenting I think is a massive challenge. Even if there's an amicable agreement between the parties, it still becomes hard.”
The journalist told Sarah Harris and Melissa Wilson that there are ways to ‘navigate’ co-parenting,’ but there’s no ‘textbook’ answer.
“You're leading separate lives, you're no longer in a co-environment. So co-parenting... that's a big word,” Cassandra began.
“There obviously is a way to navigate it. I don't think there's a textbook of instructions in point form (where) you can guarantee you're going to get that end result,” she said.
