I agree. I think that she should be more cautious and not post on social media that much with her partners because at the beginning everything is perfect but it all can change quickly. She just had had an awful and super short marriage and then she started with this boy. I saw that she deleted a lot of pictures -most of them with her previous boyfriends, so that would be something to take into account in the future.
As I can see, her longest relationship has been with Mark Wystrach, that handsome musician who has had a child recently. You commented it some days ago, they were engaged but never got married and they looked too good together, also with Jake Gyllenhaal.

Btw I can't wish her nothing but the best. I hope that the album will be finally released even they're no longer a couple.
