Married pro dancers Katya and Neil were thrown into the spotlight last month after pictures emerged of Katya kissing her celeb partner Seann.
The pair - who have since been eliminated from the competition - apologised for what they branded a 'drunken snog'.
As they try to mend their personal relationship, it's claimed that Katya and Neil are at risk of losing their place on the show.
"January is when the new cast contracts are issued and this year there is massive panic from the dancers about their futures," a source told The Sun newspaper. “Katya and Neil are worried bosses feel her dalliance with Seann has left a black mark that can’t be removed against their names."
The tabloid reports that other pros are also worried if they will be asked to return.
“Others are also panicked. Everyone feels that they have to be on best behaviour," the insider added.
A Strictly spokeswoman told the publication: “We never comment on contractual matters.”
This year's pro line up has seen newbies Italian Latin Champion Graziano Di Prima, Professional South African Latin Champion Johannes Radebe and four-time winner of the Italian Dance Championship Luba Mushtuk.
They joined Neil and Katya alongside returning Strictly professionals AJ Pritchard, Aljaž Škorjanec, Amy Dowden, Anton Du Beke, Dianne Buswell, Giovanni Pernice, Gorka Marquez, Janette Manrara, Karen Clifton, Kevin Clifton, Nadiya Bychkova , Oti Mabuse and Pasha Kovalev.
But we lost two Strictly pros: Brendan Cole, a series original, and Chloe Hewitt, who joined in 2016, both left the show this year.
