The proud mum was spotted getting playful with her young dance partner Marco De Angelis, as the pair arrived at the KISS FM studios in Sydney.
Cass was seen beaming in a blush pink tank top and jeans, pushing the hair back from out of Marco's face.
Cass spoke out about her decision to tango back onto our screens.
Speaking with The Herald Sun last week, she said “Dad said to me ‘if you don’t say yes to an opportunity that you NEVER thought would come up you will regret it one day’. Plus, learning to dance is so lovely. What a skill."
