Why is his personal life relevant or even known to the audience?
it's known because both he and his ex wife started a twitter hate war between each other and made it public. it all started when Jared made a tweet announcing he was getting a divorce. but at the same time, he had blocked his ex wife so she would not be able to see his tweet. and then she found out through friends. and was mad that
1. he made the divorce public
2. he blocked her
3. that he was leaving out details and was making it seem like he didn't do anything wrong. and refused to own up to what he did to cause the divorce
so she got fucking pissed off as all hell and fired back at him. and now we know everything cause Jared, Heidi and Holly are engaged in a very public and fierce hate war
