In 2003, Shirley split from her husband of 18 years, fellow professional dancer Corky Ballas, when it was revealed that he’d been having an affair with Kristina.
However, the new addition to the ‘Strictly’ judging panel and self-professed “people person” has insisted she holds no hard feelings towards Kristina, despite their history.
Speaking to the Daily Star, Shirley said: “I’ve had lunch with Kristina. I’m a people person. I love people.”
Shirley even went as far as saying she’d be happy to sit on the ‘Strictly’ panel should Kristina - who left the show at the end of 2015 to appear on ‘Celebrity Big Brother’, and has since given birth to her first child - return to the show in the future.
She added: “It would be absolutely fine. I have no issues with anybody being on the show at all.”
Prior to her appearance, she revealed she plans to not pull any punches when it comes to her critiques despite being the newbie, claiming: “I will be quite strict. To really impress me, the celebrity will have to have elements of technique, creativity and also the magic with your partner – chemistry.
“I’m bringing 40 years of dance experience along with all my coaching and judging so you better pull your socks up and be ready.”
Following this year’s launch, the 15 couples will hit the dance floor for the first time on Saturday 23 September on BBC One.
