Hailey Bieber Gets Real About Marriage With "Best Friend" Justin: "Still Does Take a Lot of Work"

"I struggle with finding peace. I just feel like I care so much and I want things to be so good and I want people to like me. Hailey's very logical and structured, which I need. I've always wanted security — with my dad being gone sometimes when I was a kid, with being on the road. With the lifestyle I live, everything is so uncertain. I need one thing that's certain."
