I think these are the articles people have talked about (sourced from Josei Seven which published something yesterday/today)? Or something similar. It mentions the ex-wife and a model. The model apparently gave birth late last year? I don't think he's been with RYON RYON for a while since he changed his name back to his own family name years ago so it was after they separated.
If anything, this is just unraveling drama around Maro and Ayu just so happens to be a part of it and will probably take most of the criticism since she's the 'star' of the couple. They also bring up Mannie and his comments about "Ayumi is my wife / We are not divorced" earlier this year.
