After achieving personal best scores last Saturday, both Christine and Austin are on a mission to master the Cha Cha this weekend.

Christine revealed that the "flirty and fun" Cha Cha is a dance perfectly suited to her personality, while Austin is also looking forward to showing his cheeky side.

On the topic of top boy Austin, Christine pledged defiantly, "I'll have to hope my hip action will be better than his - he's Mr Ballroom, so I'll have to be Miss Latin. I have to make Austin quake in his boots!"

There's also plenty to look forward to in Austin's routine. At one point during his dance, Erin grabs hold of our sport star's bum, which Erin describes as buttocks of steel!
