Hailey Baldwin Reveals the Beauty Product She and Justin Bieber Are Down to Share

In marriage, many couples adopt a certain "what's mine is yours" philosophy. Sometimes it's just easier to sneak a little bit of your partner's favorite product from the medicine cabinet, after all. This mentality doesn't fly in all situations, but for Hailey Baldwin and Justin Bieber, there's at least one hair product the newlyweds both reach for.

"My husband, Justin, and I actually share the same Unite shampoo in our shower," the 22-year-old told Marie Claire, revealing that most days she pairs the shampoo with her Mane 'n Tail leave-in conditioner.

"We definitely don't share skin care, though!" she continued. "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."

We all draw the line somewhere! Skin care may be off-limits, but since Baldwin is such a huge fan of her husband's scent, we do hope Bieber lets her steal his cologne every once in a while.
