I wouldn't be surprised if his girlfriend is posting that to try to make it look like Katy is still in their lives. Like people have said, that process apparently takes years.
!! Lukasz's family was dragging Katy for not speaking up in his favor just the other day
I mean she can work with however she wants but idk why she always has to work with him they're probably really close but its like she HAS to she can make hits with other producers especially if she still has Max.
There is NO evidence against Luke, in fact there's only evidence to the contrary, so I don't see what's wrong with her being friends with him. It's quite disgusting that people jump to the attack of a man based on a fruitless accusation!
