The reality TV star and wife of comedian and presenter Paddy McGuinness wrote in her autobiography A Beautiful Nightmare that a holiday to Spain had ended in A&E on the first day thanks to the accident caused by trying to live out her dream.
Christine explained: "He (Paddy) lifted me up and I sort of went over to go into the water and I cut my chin open at the bottom of the swimming pool.
"Then I had to go to the hospital and get stitches on the first day. After that I couldn’t go into the water or sunbathe.
"I just wanted to be in Dirty Dancing and I bloody cut my chin open."
The 1987 film is known for a scene in which dance teacher Johnny (Patrick Swayze) lifts Baby (Jennifer Grey) over his head in the water to show her a lift he performed with a pro dancer, which seems to be the move the McGuinnesses were trying to achieve.
Her memoir details her life with the Top Gear presenter and their three young children, who have all been diagnosed with autism - as has she as an adult.
The couple have often spoken about the challenges they face in their home life and in a recent interview with The Mirror, Christine also talked about how her husband helped her to deal with her own autism.
She admitted that she often avoided going to restaurants because she found it stressful if strangers tried to talk to her and worried about getting her order wrong, but said that husband Paddy would usually order for her to make her feel more at ease.
Christine added that they had celebrated Valentine's Day early on Thursday with a day out in Manchester before the children finished school for half term.
She said: "We aren't going to be able to do that on Valentine's Day as we'll have the three children with us."
