ET spoke to Kat in October and she talked about why she was mostly private about her dating life.
"I don't share most things and it's not because I I have any secrets or anything, it's just that I have found that when I've shared very personal things, you know, like, I'm dating or whatever it is, like, it kind of feels icky," she said. "Just there's there's something about letting a huge amount of people into your life that, it just depends on your personality. Some people have no issue and are kind of an open book and I've just learned over the years ... it doesn't feel good for me. But any detail about my personal life, I've now kept to myself just because it just doesn't feel good."
