The professional dancer, who this series is partnered with DJ Goldie, had an operation to remove a benign ovarian cyst.
“It was a really scary experience because I want to have children one day,” she told HELLO!magazine, as she and Joe posed for an exclusive photoshoot at their home in Wales.
The health problem occurred in the early days of her relationship with Joe, and she admitted she was unsure of how he would react.
“It’s one of those things that can test a relationship,” said the Latin and ballroom dancer who was married to American dancer Brian Jolly for five years and had relationships with Corky Ballas, a professional dancer on US show Dancing With The Stars, and her Strictly co-star Vincent Simone.
Joe, however, was a tower of strength. “Joe was just there for me,” said Kristina.
“He took me to the hospital, brought me back to Wales, was around me 24/7, feeding me, helping me, and that’s when I was just taken so deeply by how caring he is.
Joe, who has two sons with his ex-wife Mandy, and previously dated model Jo-Emma Larvin for five years, feels his relationship with Kristina is special.
“She’s [Kristina] the person that I’ve gelled with most out of anybody in my life.
