She said: 'It was a whirlwind romance. He really did sweep me off my feet. Looking back now, I would say he was the wrong person for me.
'Most people around me now, my close friends, say, 'We saw that at the time'.
'I'm like, 'Thanks for telling me!''
Dannii also told how she supported Julian as he struggled to establish himself as an actor after their 1994 wedding.
She also told how she did not get on with Julian’s mother, Lady Sonia McMahon.
'It was made clear to me I was not welcome in the family at all, to any family events,' she said.
'Julian also said to me if he was doing family things he was going to go on his own. I don't know why I wasn’t welcome. I didn't talk to Lady Sonia about it. There was no relationship between us.'
Talking about the end of the marriage, she said: 'It felt like all my innocence had gone. It was over so fast. I was not only broke, but in debt.'
