The 28-year-old actor — best known for playing Sinead Tinker in Coronation Street — is taking part in the BBC dance contest this year and said the late TV presenter, who won the show in 2014, is her biggest inspiration from past series.
McGlynn told Yahoo UK: "I think Caroline Flack was just incredible. If you if you watch her journey throughout it, she was just insanely amazing."
The Hollyoaks actor is a huge Strictly fan and admits it is entertaining to watch the judges deliver harsh criticism of the contestants on the show.
But McGlynn doesn't think she'll be able to take it if the judges are too mean to her.
She said: "When I watch it on telly I love the drama — I don't like it when they completely take the Michael out of the contestants, I think it's mean — but sometimes it is quite funny.
"But when it's me I'll probably just go quiet and not say anything, or cry!"
And the soap star insists she will struggle to act 'sexy' on the dancefloor.
McGlynn said: "I am just not sexy! I'm really awkward. I'm hoping on the day that I do these dances, I'm just gonna morph into a different character, because I'm such an awkward person."
Comedian Robert Webb, actor Greg Wise and EastEnders stars Nina Wadia and Rose Ayling-Ellis are also among the stars taking to the dancefloor in the hope of winning the coveted glitterball trophy.
Judges Craig Revel Horwood, Motsi Mabuse and Shirley Ballas will be back, but Anton Du Beke will be filling in for Bruno Tonioli.
Tonioli is unable to take part because of the complications of travelling between the UK and the US, where he judges Dancing With The Stars, amid the COVID pandemic.
