When I meet the couples at Elstree studios in Hertfordshire, they've been busy practising for the group routine.
Not everyone showed up for the interviews. Former Apprentice star Thomas Skinner dropped out of his slot the night before.
Skinner also walked out of a press event early, after seeing a message on a reporter's phone which - he later said - "caught [him] off guard".
I asked the celebrities who did turn up, how the training was going.
"It's hard for me to let go of the whole, 'I don't dance' thing, and just fully get into it, but that's what I want to do. And I feel like I've started a bit... maybe," said YouTuber and podcaster George Clarke, 25.
Clarke also told me he was ready for some hard home truths about his moves.
"I think it would be silly for me to turn up and think, week one, well, I'm going to go out there and the judge is going to say, 'I've never seen anything like this'," he said.
"I'm inviting it, because I think I'll most likely be like, that's fair enough."
Former Team GB sprinter Harry Aikines-Aryeetey - also known as Nitro in Gladiators - is no stranger to performing in front of audiences.
But the 37-year-old said Strictly is "totally different" to anything he's used to.
"I'm learning more about myself through the process," he said.
"Obviously, I'm not trained in any capacity in this way of life," he added. "So I'm quite excited to see how I deal with that."
