And - not at all surprisingly - her former bandmate from The Saturdays' Frankie Bridge is one of them.
Frankie made the final of the show in 2014 - can Mollie do as well?
"I’m really looking forward to genuinely learning to dance with my partner," she said this week. "Of course, performing every Saturday night is going to be so exciting, the costumes and I love a cheeky spray tan.
"I’ve spoken to people who’ve done the show before like Frankie Bridge and Laura Whitmore and they’ve both said that they’ve had such a blast doing it so I can’t wait to get stuck in!"
Mollie went on to play down her past dance experience, saying: "I’ve performed with The Saturdays, but we never really did full on dance routines, it was more just poses or moving around the stage. I’ve never actually done anything like this.
"I went to a ballet class when I was about three and they told my mum that she was wasting her money taking me there because I had no grace at all, so my mum took me out and took me to football class, so I’m hoping I’ll be a bit more graceful now."
In tonight's launch show, Mollie will discover who her professional partner for the new series is.
As for what she's after in her pro dancer, Mollie said: "Somebody that’s very patient as I’m quite slow to pick things up.
"Someone who can have a real good laugh, somebody that I really get on with and who’s going to really help me but be able to have a laugh with it too."
Mollie added: "I’d love to get as far as possible. I’d love to get to Blackpool but I know obviously that that’s really far off. I’d love to get as far in so that I can have soaked up the atmosphere, the costumes, the fake tan, just so that I’ve lapped it all up really."
Strictly Come Dancing 2017 starts this Saturday night on BBC One at 7PM.
