While on air, the fact that a lot of dancers 'hook-up' with each other was pointed out to the Thorburn: "A lot of the dancers hook up with the people that their dancing with and this season you’ll be free to do that," joked the radio hosts.
Cassandra replied making it quite clear that unlike her ex-husband, she is not interested in dating younger,
“Exactly! Except that my dance partner happens to be 24 years old so I'm not sure."
