The 22-year-old model opened up during an appearance on Kendall Jenner’s Zaza World Apple radio show on Thursday. When asked to give a summary about their nuptials, she didn't hold back.
"It's a scary thing, but it's also the person that I've literally been in love with for so many years," Hailey said.
"I feel like he's my best friend," she added. "And we just get to do life together forever, now. I think the forever aspect for me is just like, you don't think about that until you get married. And then you're like, OK, this is really like, this is forever. Meaning like, there is no end."
While she enjoys being Mrs. Bieber, Hailey reveals she finds it difficult to put someone else's needs ahead of herself, but they're making it work.
"I've always been so independent," she said. "So for me, trying to cohabitate with someone and learn how to like, do life with another person, that directly has just been interesting. It's so different."
Their most recent test comes after news broke that Justin is seeking treatment for depression.
Hailey has been doing her part because she's been spotted by his side showing she's a loving and supportive wife.
