Both pro dancers left the series this autumn and although they've gone, they're still making headlines.
It's been reported this weekend the duo spend the last two years on the show locked in a 'jealous' battle over who would be top dog.
The Sun newspaper reports that Ola and her fellow Strictly pro husband James Jordan are set to spill all about the clashes in a new tell-all book.
But they don't plan to name Kristina to avoid coming across as "bitchy".
Fortunately, a 'Strictly source' has spilled all the beans.
“Ola and Kristina were friends but jealousy took over and it created an incredibly uncomfortable atmosphere for all of the pros," they claimed to the tabloid.
The supposed insider went on: “James wanted Ola to take centre stage as the main star of Strictly and Kristina hated that. There were many whispers and rumours spread about each other and the friendship ended.”
And they added: “The reality is most of the dancers are very happy and get on. But trouble seemed to follow Ola, James and Kristina wherever they went.
"Put it this way, no one is upset about them not being around this year.”
Alongside Ola and Kristina, other pros to leave Strictly this year are Aliona Vilani, Tristan MacManus and Gleb Savchenko.
New faces in their place are World Champion Katya Jones, Ukrainian Champion Oksana Platero and top Spanish dance professional Gorka Marquez.
Also joining are a trio of British dancers including World Champion Neil Jones and British and European Youth Latin and Ballroom Champions, AJ Pritchard and Chloe Hewitt, who will be the youngest ever professional dancers to appear on Strictly Come Dancing.
Strictly airs on BBC One on Saturday nights.
