Alaia Baldwin Is an Actress - Facts about Hailey Bieber's Sister Diagnosed with Endometriosis

Alaia Baldwin Aronow is the daughter of Stephen Baldwin and the older sister to famous model Hailey Bieber. She is an actress and model from a long line of Hollywood entertainers. More recently, she became an activist for endometriosis after her diagnosis.

Hailey Bieber, formerly known as Hailey Baldwin, started her married life when she quietly married Justin Bieber in a courthouse in New York City in September 2018.

After marriage, Hailey Bieber revealed that she would not give in to societal pressures that dictated that having children was the next step in her life's journey. She would instead focus on growing her business.

Despite wanting to have kids while she is young, Hailey believes she still has time for that, and her husband supports her fully. Justin said:

"I'm going to have as many as Hailey is wishing to push out. I'd love to have myself a little tribe, but it's her body and whatever she wants to do."

Justin does not see it as an issue that Hailey wants to accomplish other goals before having kids. Meanwhile, as she enjoys her time with her hubby, she has enough love for other kids, especially her niece.

Alaia Baldwin Made Sister Hailey an Aunt

Hailey became a first-time aunt when her older sister Alaia welcomed her firstborn, a daughter, Iris Elle Aronow, on August 17, 2020. The new mom had taken to Instagram to announce the birth of her daughter while thanking their doctor.

Shortly after Alaia announced this on Instagram, an excited Hailey shared the photo of her sister on her Instagram Story. She told her fans that keeping the news to herself was hard.

Hailey described her niece as beautiful and perfect while mentioning that she already loved her so much. She and Justin wasted no time visiting the newest family member.

Hailey held the baby to her shoulders as she supported the baby's head and back with her hands while posing for a picture.

Endometriosis is a chronic illness in which endometrial-like tissue forms on organs other than the uterus. It affects an estimated ten percent of women of reproductive age, and it takes an average of ten years to receive a proper diagnosis.

In 2020, she joined the Endometriosis Foundation of America, EndoFound, as a junior board member and became an ambassador. She wants to use her platform as a model to spread awareness.
