Strictly Come Dancing star Kym Marsh has revealed her "worry" about her next live performance on the show, due to a condition she suffers with that can make her "feel weird".
This weekend, Kym and her pro dance partner Graziano Di Prima will perform the Viennese Waltz to the song Runaway, by The Corrs.
The particular dance features lots of fast spins, and twirls - something Kym is a little worried about as she suffers with visual vertigo.
Kym revealed that moving lights as well as slight spinning can cause her to feel nauseous and dizzy.
Her worry is that with all the spins in her routine, especially an added element Graziano has tasked her with, she might not get the performance right.
Speaking on It Takes Two to host Rylan Clark on Friday, she revealed: "Well, you see I have got visual vertigo. I had an ear problem about six years ago and it left me with visual vertigo, so basically even moving lights make me feel weird.
"I can't do it, so spinning and spinning, there is a particular part in this routine where I am spinning so fast and then he [Graziano] wants me to get up and do a turn on my own.
"Well, I can't do them at the best of times so I am literally like, 'Oh my, what am I going to do here?' That's probably the bit I'm most worried about."
Kym is giving it her best shot though, and added: "But you know what, it is what it is and I can't help having the thing that I've got so I am just going to do my best and my best is all I can do."
Also on the show, Kym revealed she wasn't as confident as people expected her to be, as she revealed all on her nerves.
Rylan said to her: "We all thought ‘Kym's not going to worry because she’s used to performing at arenas’".
Kym addressed this, saying: "You know what, I am probably one of the most unconfident people."
Graziano agreed with this, sharing his own surprise about it, He said: "It was a massive surprise for me - obviously we knew each other but not a lot. And people always say ‘she’s going to be super confident’ but she’s not.
"I want to tell you here, in front of everyone, you are brilliant...she doesn't believe that!"
Rylan praised Graziano for his support for Kym, and said: "I don’t think I could fall in love with you anymore," before adding to Kym: "You said you were nervous but none of us had a clue."
Strictly's It Takes Two airs weeknights at 6:30pm on BBC Two and BBC iPlayer.
