The episode, which airs at 7pm, will feature Rice, 60, surprising her professional dance partner Kevin Clifton with a helicopter ride and giving him an insight into her days presenting Treasure Hunt.
Snaps from the episode reveal Rice even sported the original Treasure Hunt jumpsuit.
The dancing duo have also been busing rehearsing for their performance, a Cha Cha Cha to Laura Branigan’s Gloria.
Rice tells Clifton: “I’m feeling about the Cha Cha Cha like you’re feeling right now…”
The TV presenter, who is best known for fronting game show Challenge Anneka on BBC One, previously said that she was feeling “recklessly excited” to join the show – but suggested that her children will “probably leave the country” after seeing her dance.
“I haven’t danced since I was seven and Miss Beer sent me home from my ballet class because I was hopelessly uncoordinated,” she said. “My family and friends haven’t seen me dance since, not at a wedding or round a handbag so it’s going to be a challenge for my partner.
“In fact I’ve asked for two, one on each side. I can’t see myself in a long frilly dress either. But I’m feeling recklessly excied. Strictly has always been my autumn’s entertainment and now I’m part of it! Mt children will probably leave the country.”
