In December, Lilly reflected on the past year amid her split from her husband of nine years during an interview with Günther Jauch on Germany’s RTL.
The brunette admitted the couple will never rekindle their relationship, insisting: ‘It’s really over between us.’
Reflecting on the past year, the Dutch beauty bluntly said: ‘2018 was the worst time of my 42 years. He so grossly disappointed me.’
Speaking on the negative effects of being in the limelight, she went on: ‘What makes it so bad is that everything is happening in public now. But I married a public man, maybe it’s part of it.’

Lilly added that the pair’s priority is their son: ‘The most important thing is that the future of Amadeus is well arranged. It’s not about Boris or me.
Boris and Lilly confirmed their breakup via a German lawyer last year, in a statement given to Bild newspaper.
Lawyer Christian-Oliver Moser said: ‘The decision after a 13-year-long relationship and nine years of marriage wasn’t an easy one.’
