'Strictly Come Dancing' bosses fear a huge showdown between the professional dancers.
Kristina Rihanoff
Rehearsals for the BBC dance competition are due to begin on Monday (03.08.15), but pro dancer Kristina Rihanoff - who is in a relationship with her former contestant and dance partner Ben Cohen - has riled her co-stars by listing other professional dancers who have had flings with their celebrity dance partners and colleagues, including Janette Manrara, Pasha Kovalev, Flavia Cacace, Artem Chigvintsev and Aljaz Skorjanec, in order to defend her own romance.
A show source said: "A lot of the dancers are expecting fireworks on Monday because of everything that has been going on."
Some of the pros are also annoyed that Ola Jordan has been called back for this year's series, having injured her leg on Channel 4's 'The Jump last year, forcing her to pull out of the group dance in the 'Strictly' final.
The insider told the Daily Mirror newspaper: "Some of them think she is receiving preferential treatment as she was hurt appearing in another show but still managed to get round bosses."
The source went on to insist the line-up for the BBC show - which starts in September - is still "up in the air", despite the likes of Michelle Heaton, Jamelia and Peter Andre rumoured to be taking part.
