According to The Sun, the pro-dancer is “stressed” out about how the speculation could affect their place in the competition.
“She denies anything is going on but doesn't help herself by constantly cuddling up to him and flirting. That encourages speculation, which stresses her out and affects her performance.”
However, former The Wanted singer Jay has insisted that there is nothing going on between him and Aliona, after pictures of the pair hugging outside an awards bash were published.
“I am single but I didn’t expect to meet someone on ‘Strictly’,” he said.
“Aliona is happily married to an Irish fellow who I think is a legend. So my eyes won’t wander in our rehearsals.”
