Think this
blind from Blind Gossip is pretty right, what Zayn did was inexcusable but Yolanda is a terrible mother who wants to live vicariously through the fame she’s engineered for her children. Seeing what Bella did to her face to become ‘acceptable’ is shocking and at best she passively let her way too young daughter have those procedures without intervening, and at worst she actively encouraged it. She is toxic as is Zayn, neither of them come out of this covered in any glory. There is no excuse, nor ever will there be for him being verbally and possibly physically aggressive to a woman, even if that woman is unpalatable to say the least. She needs to have a long hard look at herself though too (which I’m sure she won’t). She’s pushed her children forward to be the celebrities she craved them to be with little or no thought of their well-being and mental health and has been hugely abusive to them as a result. I also think she has a form of munchausen
this gives a good breakdown of how the Lyme disease she reckons practically the whole family had just wasn’t possible.
