The band first announced the change via a statement that the "parting ways was agreed by all members" but Kristine posted her own message online, saying in part, "I was told a bit longer than a week ago that I am not preferred as the band's singer for further tours and recordings anymore.

"I asked for the situation concerning Indonesia and the soon-to-happen up-coming shows. The answer was 'no'. I asked if there's a replacement and I got no clear answer. I can't believe this process happened behind my back, parallel to a huge disappointment in my private life. A few days later there certainly was a replacement. I must say - that was 'quick'!"

The band fired back on Tuesday by posting photos of the protocol documents for the separation and saying, "Since we are fed up with the lies on social media, and as we promised yesterday, here is the proof that we tell you the truth about what is going on.

"Here you can read the signed protocol documents (English and German) - certified by lawyer Frank Dehn - which proves that the news about the protocol from the mediator of our crucial band meeting is accurate and correct in every way.
