She followed 3 accounts in a row between Sunday and Monday, idk, maybe it's her agency who did it, since we know they sometimes post something on her ig, specially work related. Or it was just her that was checking out her tag and decided to make happy a few fans, who knows. Anyway it was a nice gesture, having experienced it myself I know it feels very good to be aknowledged by someone you admire and are a dedicated fan of. Imo she could do this a bit more often, having such a huge and dedicated fanbase that supported her all this years. I'm not saying she doesn't appreciate us fans, all the contrary she always thanks us in interviews as one of the factors of her long career success, but little gestures like this are way more common from other models that don't have this kind of dedicated support.
