Cannon continued, “I wanted to definitely respect the grieving process with Alyssa, and Bre was respectful enough — She held off making our announcements and speaking on social media. She’s a very, you know, in the public eye type of person, but keeps her stuff private as well.”

The dad added, “And it was just one of those things like, you know, I didn’t know what to do. I didn’t know what to say when I was dealing with Zen or to hold off. Even right now, that it came out yesterday, that wasn’t planned to talk about it. We wanted to, you know, hold on as long as we can, but it happened. We here and I’m with my family I get to discuss it, I get to be open.”
