Relations between Holly Valance, Lulu and Dan Lobb and their respective partners Artem Chigvintsev, Brendan Cole and Katya Virshilas are apparently "extremely tense", causing chaos as the BBC prepares for tomorrow's (December 17) Blackpool Tower show.
Lulu is believed to be "livid" with Cole over comments the professional made about her after Strictly, while Valance and Lobb have apparently been accused of lacking in dedication and ability while competing.
"Lulu was livid," a source told The Sun. "I'm sure he didn't mean to upset her but she has been very sensitive about her time on the show and needed more support than he was prepared to give her. He is a very hard taskmaster and this didn't often sit well with Lulu.
"As for Katya, she thought Dan didn't care. But Dan has been telling people he thought she was getting all of the attention when it should have been about them as a couple."
A show insider added: "All these difficulties make bringing together such a huge show like the Strictly final tougher than it should be. But all the celebrities and dancers are professional people and bosses are hoping that nothing will spill over into the show."
Harry Judd, Chelsee Healey and Jason Donovan will compete in the Strictly Come Dancing final, which airs Saturday, December 17 at 7pm on BBC One.
