Justin Bieber and Hailey Bieber attend the premiere of YouTube Original's "Justin Bieber: Seasons" at the Regency Bruin Theatre on Jan. 27, 2020 in Los Angeles.

Hailey Bieber is opening up about "the beauty of what being in a relationship is" -- and which beauty tool she and husband Justin Bieber share on a daily basis.

The 24-year-old bareMinerals clean beauty ambassador told People on Tuesday (Feb. 24) about the healthy habits -- such as liver detoxes -- the couple has been adopting during the pandemic, which has allowed them to spend more time together.

"Both my husband and I are really healthy, so sometimes we'll do it at the same time," she said. "I did a cleanse where I was flushing my liver and just drinking a ton of water and juice and tea and soups. There's so many different things you can do, like sitting in a sauna is detoxing or an Epsom salt bath."

But that's not the only consistent part of their beauty routine: Of all the "random" tools they could swap, she said they "use the same hairbrush all the time."

"I feel like when you're married or you live with someone, you just start to use each other's sh--," the model explained. "I wouldn't even bat an eye if I walked into the bathroom and he's using my eye cream or something. That's just kind of some of the beauty of what being in a relationship is!"

The couple also share matching ink that they got in 2018 from celebrity tattoo artist JonBoy, aka Jonathan Valena of Bang Bang NYC. He shared a close-up shot of the 26-year-old singer's face tattoo that reads "grace" above his left eyebrow. Last October, she got "J" with a star tattooed on her ring finger to commemorate her pop star husband.
