When Justin first proposed to Hailey, he was worried that he wouldn't be faithful to her. On Ellen yesterday he opened up and said, "I think that was really what I was battling with. I finally was like, 'I'm going to make the decision and follow through with it and be a husband.'
"This is what I always wanted. I'm going to just choose this woman and just do it."
Hopefully he sticks to what he says. Watch the full interview below.
