Hailey Bieber is taking a private struggle public, and putting real money behind it. The Rhode founder and skincare mogul revealed she battled premenstrual dysphoric disorder, or PMDD, in the months after giving birth to her son Jack Blues in August 2024, her first child with husband Justin Bieber.

"After I had my son, I struggled with that a bit, and there's just not a lot of conversation or research around it," Bieber told WWD in an interview published Oct. 30, calling the condition a "lonely journey" that left her searching for information that simply wasn't there.

PMDD is a severe, hormone-triggered mood disorder that hits in the two weeks before a menstrual cycle begins, producing depression, anxiety and irritability far more intense than typical PMS. Bieber said postpartum hormone swings made her case especially brutal, and that she found relief mainly in talking about it.

"Conversation, for me personally, makes me feel less alone."

Rhode's $5 million bet on women's health

Bieber isn't just sharing her story — she's funding the search for answers. Her beauty brand Rhode is committing $5 million over three years to the Foundation for Women's Health, the brand's largest philanthropic pledge to date, according to WWD's reporting. The money is earmarked for research into conditions like PMDD and endometriosis, which Bieber says have touched people close to her.

E! News and TMZ both picked up the interview Tuesday into Wednesday, amplifying a disclosure that fans and health advocates online have called unusually candid for a celebrity with a beauty-industry bottom line to protect.

This isn't Bieber's first time cracking open her postpartum experience. Back in March, she appeared on the "SHE MD" podcast and discussed a uterine septum diagnosis that made her pregnancy higher-risk than expected, along with postpartum anxiety and recovery. Tuesday's WWD interview goes further, naming PMDD specifically and tying her disclosure to a concrete financial commitment rather than just a conversation.

Bieber and Justin Bieber, who married in 2018, welcomed Jack Blues in August 2024. She has been candid in the past about other health scares, including a 2022 mini-stroke tied to a heart condition, but PMDD represents a newer, more hormone-specific chapter in her public health narrative.

What's next: Rhode says the Foundation for Women's Health partnership runs three years, with research outcomes expected to roll out over that window. Bieber has not said whether she sought treatment for PMDD or how long her symptoms lasted, leaving some of the medical specifics still private even as she makes the broader disclosure.
