Was Aamir and Fatima Sana Sheikh’s affair ever real?

I’ve always wondered if it’s just speculation, or the fact that it could’ve possibly just been a deep bond formed via Dangal and its themes. The rumours of his marriage with her, tied along with his own divorce from Kiran…somehow everything leans towards an affair but at the same time doesn’t.

Does anyone have tea/proof about this being real in any way?
