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.
