Breaking down in tears at Fearne Cotton's Happy Place Festival at Gunnersby Park, Davina said: 'I needed to get my brain in the right place where I could be calm before the operation.'I had to make sure that my kids were going to be OK if I did not make it. That is all I really cared about.'I knew my partner, Michael, would be OK as he is a whole person, but I was really worried about my kids. The mum of three who shares Holly, 23, Tilly, 21, and 18-year-old Chester with her ex added: 'I went into forensic thinking about my children and where they were at in their life, what stage they were at.
