She was pretty upset about it
Not what I'd call a celebrity, but Pete Wentz broke my friend's phone a couple years ago. My friend was texting someone, didn't even notice yon douchebag, and he comes storming up to her, grabs the phone and smashes it to the ground, snarls something about how it'll be her face next.
My friend was a fangirl, so she was pretty upset about it, too.
