How do Shawn’s children not know about who he’s dating?

I find it hard to believe that at least one of his three children doesn’t know who he’s dating yet. He’s already been on Love in Paradise a year ago, and added a photo on his Instagram of his 90 Day premier last year. Being in an industry where there’s a lot of chatter, it seems nearly impossible that his ex wife or children haven’t already found out.

Is Shawn estranged from his children or are the producers scrambling for a story?
