Kelvin Fletcher, 35, admitted he was struggling with the twists and turns on Strictly's official podcast with host and former contestant, Joe Sugg and Kim Winston.
The actor said that during the first day of training for the dance with his professional dance partner, Oti Mabuse, the constant spinning in the dance made him unwell.
“I was sick for the first time on Monday,” he said: “That has always been my biggest fear with anything ballroom. With the waltz, especially the Viennese Waltz, it looks so beautiful and effortless and flows.
“The spins, they look so stunning but I fear them because the minute I start spinning my head goes and on Monday I was in the toilet and it wasn't pretty,” he explained.
