The 22-year-old model - who tied the knot with the 'No Brainer' hitmaker last year - is often pictured sharing her beau's sweatpants, especially pieces from his new clothing line, Drew House, however, the star has revealed that although they use the same products in the shower, they "definitely " don't share skincare because Hailey's moisturiser is made from her own blood.
She said: "My husband, Justin, and I actually share the same Unite shampoo in our shower. We definitely don't share skincare, though! I moisturize with a cream by Dr. Barbara Sturm that's formulated with my blood, so I don't think he wants to put something that was made from my body on himself.
"My skin is really sensitive, so I'm not a huge fan of facials with extractions, which are too hard on my skin. I'm into treatments that are really soothing, like HydraFacials, which use water and suction to cleanse.
"At home, I use a good hyaluronic-acid serum, SPF, and my blood cream. And I try to avoid formulas with fragrance so I don't break out, especially after being on set all day where I don't know exactly what's going on my skin."
The blonde beauty also admitted that her mother, Kennya Baldwin, is her "beauty muse" because she taught her how to take care her skin.
