The 28-year-old children's entertainer told The Daily Telegraph on Thursday that she was behind the decision for the couple to end their marriage, claiming they were both unhappy.
Watkins added the couple parted ways during a very challenging year that saw her undergo several health scares, including surgery for endometriosis and a leukaemia scare.
Following her endometriosis surgery, the Daily Telegraph reports Emma had to undergo a blood transfusion and at one point, she faced the possibility that she might have leukaemia.
'It has been a weird time for us. I think we just realised that we were meant to be best friends,' she told the publication.
'I wanted to make the decision to separate…I am very independent and my mum keeps telling me that no one is going to be able to tell me what to do.'
Continuing, Emma said, 'We are not really cranky at each other, we just realised that our situation had changed...probably more from me, than from him.'
Emma and Lachy announced their split in August. However, the couple actually split earlier this year - with purple Wiggle Lachy moving out of their Sydney home in February.
The pair continue to work together as part of the children's group, The Wiggles.
