Justin and Hailey Bieber find ways of "sharing responsibilities"

The 29-year-old model - who is the founder and chief creative officer of the Rhode skincare brand - said during Vogue's Forces of Fashion event in Australia: "Having a great partner is really important. And sharing responsibilities.

"I'm here working and my son is at home with his dad living his best life. Having that support is very freeing and makes the decision a little bit easier."

Hailey also revealed that she loves to collaborate with her husband.

The model - who married Justin in 2018 - shared: "I'm always super excited to collaborate with the person that I love.

"[Justin and I] don't think of it as a work thing. We look at it as, 'How fun is it that we can both do the things that we're passionate about, so let's do something that we're passionate about together.'

"We're both people that really love things that feel effortless and seamless, and want to do things that feel fun."

Hailey explained that motherhood has served to sharpen her focus, too.

She said: "I am a very big believer in our 'nos' being more powerful than our 'yeses' and becoming a mom has made me refocus on what's important to me.

"Sometimes it's hard and painful to say no to things, but I also think that saying no ends up serving you more in the end, because then you can show up in other spaces at your best self."

Meanwhile, Hailey previously revealed that motherhood has made her "a lot more of a homebody".

The model told GQ magazine: "A typical day at home for me is I get up with my son, hit a workout as much as I can.

"I've become a lot more of a homebody than I used to be. And I think when you have a child, that happens, at least it did for me. It definitely made me have so much less FOMO.

"I just love to spend time with my son. He's growing so fast and it's gone by so fast, and it starts to become more and more real how much you want to soak up that time."
