Strictly Come Dancing’s Kym Marsh reveals terrifying health condition that could ruin this week’s dance

STRICTLY Come Dancing star Kym Marsh has opened up about a terrifying health condition that could jeopardise her dance this weekend.

The Morning Live presenter, 46, revealed all about the frightening medical issue on Friday's episode of Strictly: It Takes Two.

Chatting to host Rylan Clark, Kym was in the studio with her partner Graziano Di Prima.

Talk turned to tomorrow night's routine, the Viennese Waltz, which Kym will perform to The Corrs' track Runaway.

Asked whether she felt sick from all the spins in the routine, Kym revealed she suffers from a health condition that makes it even worse.

She explained: "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?'

Kym's revelation comes as some fans blasted her Strictly Come Dancing debut as "unfair."

This was because the pair were set to dance the jive - a typically tough routine - for their debut.

One fan took to Twitter to write: "Unfair to give a jive in Wk1 but, although that was tentative and slower than we’d like, Kym presented it well and was cleaner than usual Wk1 #Strictly."

A second put: "Jive on week one always feels a bit harsh to me. Thought Kym did well being first as well. Lots of potential once the nerves reduce a bit!"

A third then continued: "Always think a jive in the first week is unfair," as a fourth wrote: "Wow to be given Jive week one that’s really tough for anyone to get #Strictly."

One then concluded: "A great first dance from Kym and Graziano. The jive is a difficult dance."

Despite the worries, the pair pulled a score of 23 from the judges.

Fifteen celebs took to the dance floor tonight for the first episode of the series and many ended up getting high marks from Shirley Ballas, Craig Revel Horwood, Motsi Mabuse and Anton du Beke.

Viewers felt that while some people were over marked, others were under scored – like Fleur East – and they demanded to know what was going on.
