She doesn't. She doesn't have any class, or decorum etc.
She's been pretty quiet since Harry's book but that's probably because she's pulled all the stings and is watching to see how it pans out and that will determine what she does next.
My bet is that she's distancing herself from Harry after manipulating on the background and causing him mh issues, anger issues, family issues etc, if she divorces him, she'll be on operah and all the rest, bleating about how it was all him, when it's blatantly obvious she wound him up and watched him go.
Now that they haven't got the outcome that she wanted, she's ready to move on.
Dior will be fools to collab with her. My first thought on reading the title of the thread was noooo, I love Dior, but won't buy from them now.
