It was reported last week that actress Kara Tointon, who started dating Chigvintsev following their 2010 victory, was struggling to control her jealousy while watching their routines.
Fresh claims suggested that Tointon had demanded a front row seat at this weekend's show to keep an eye on the pair, but Valance has revealed that the ex-EastEnders star has actually been helping them.
"Kara has been giving me lots of advice. It's not long ago that she did it and she knows what I am feeling like. That's been so brilliant," Valance told The Sun.
"It's all above board. We have become good friends and my boyfriend gets on great with Artem. That's so important. We get on great and he is a fantastic teacher, but when you are suddenly spending time with a random man, it's important that everything is above board.
"Artem is a lovely guy and I hope we do hang out after this show has finished. He is extremely passionate about dancing and whilst I tend to do things very calmly and quietly, he goes about it in more of a Russian way."
Valance recently confessed that her boyfriend Nick Candy loves her Strictly Come Dancing outfits and has asked her to bring them home.
