The BBC host, who fronts the show alongside Tess Daly, explained during a recent stint on Radio 4's Woman's Hour that she phoned the bosses "in tears" because of her fear that the show would clash with her son's move to University.
"I phoned the boss of Strictly quite dramatically and said, through tears, 'Sarah I love you. I don't want to leave Strictly and Tess and I have agreed we will leave together when they're done with us, but if the first show is September 13, I'm out and you'll have to go with somebody else.'"

The mother-of-three added: "And there was a beat. And she said, 'Quite dramatic. We don't start that week.' I was like, 'Alright. I have to go and put up his posters'. It's not that I love him more than others love their kids, but this is something parents have to go through."
Claudia shares three children with her husband, film producer Kris Thykier. The pair, who married in 2000 and live in London, share Jake, 18, Matilda, 15, and Arthur, aged 10.

The Strictly presenter is quite private about her family life, however, she has made comments before about the family-of-five's strong bond. In August 2018 she opened up about what makes her brood so close during an interview with The Guardian.
Talking to beauty journalist Sali Hughes, the down-to-earth star admitted that they live in a very open household, so much so that there are no locks on the doors.
The 49-year-old disclosed when asked if she would go to the bathroom without locking the door: "Of course, yes! And the window open… I might go, 'I'm in here', you could sit there, no problem.'"
