The Capital FM DJ confessed she chopped off part of her own finger as a child.
It left her with a slightly shorter ring finger on her right hand, although it doesn't normally affect her on a day to day basis.
But as she learns to jive with Sicilian-born stud Graziano Di Prima ahead of the launch show, Vick admitted it was an extra challenge.
Talking to the camera for a Strictly social media video, Graziano exclaimed: "We have a really big problem because Vick cannot click.
"So sometimes we laughed about that."
Vick added: "I've got quite stiff fingers.
"I chopped one off when I was little by accident.
"So not only am I learning how to dance, I'm learning how to click."
But her dance partner Graziano was singing her praises during rehearsals, revealing she works "really hard" and "likes to be precise".
Vick is still hosting the Capital breakfast show with Roman Kemp and Sonny Jay before heading to the dance studio to work on her moves.
She's being tipped by the bookies to go far in the competition, only narrowly being beaten in the odds by Pussycat Dolls star Ashley Roberts.
In an exclusive chat with The Sun Online earlier this month, Vick admitted she can't take her eyes off the "sexy" professional dancers taking part in the BBC One show.
She confessed she has already felt chemistry with at least one of her potential teachers, but kept shtum about which one.
"These dancers are incredible, have you seen them?
"The girls and boys, they're amazing! And I don't know about romances but I can't take my eyes off them."
Viewers saw the moment she was partnered up with professional dancer Graziano on Saturday night.
The pair now have two weeks to learn their first dance before performing live in front of millions.
