Hailey Bieber’s sister, Alaia Baldwin, has hoped to make a name for herself over the years despite being from a famous family.

Alaia is the eldest child of Stephen Baldwin and Kennya Baldwin and the niece of actor Alec Baldwin. “It is really frustrating because you're trying to do this on your own, but you still have that connection,” Alaia told Marie Claire of her star-studded relatives in April 2016. “For me, it's not that bad because my family's not single-handedly taking over the world at once like the Kardashians."

Bieber, for her part, told Fashion magazine in August 2017 that she and Alaia managed to have a normal childhood despite their family’s status. “The way my parents raised my sister and me, [Hollywood] was always separate — that was Dad’s work life,” she explained. “When we were home, we were just home, hanging out.”

The sisters have remained close over the years, from introducing the Jonas Brothers on Saturday Night Live together in 2009 to being a part of each other’s wedding bridal parties.

What Is Alaia Baldwin’s Job?

Like Hailey, Alaia built a career as a professional model and worked with brands such as Calvin Klein and Tommy Hilfiger. “One of my ambitions is to take this career and view it as art,” she told Marie Claire in 2016. “I think that's sort of a lost concept because everyone is so focused on social media and making money. At the end of the day when I get frustrated and get upset, I remember how much I love getting into character and creating a fashion story.”

Outside of modeling, Alaia has become an advocate for endometriosis awareness since being diagnosed with the condition in 2016. She also serves as an ambassador for the Endometriosis Foundation of America.

In March 2020, Alaia wrote the foreword for Dr. Tamer Seckin’s informational book, EndoMEtriosis: A Guide for Girls. “That’s really been a big motivation for me to share and just be an open ear to anyone that wants to have someone to talk to or who understands,” she said in an August 2020 interview about the book. “Because it can be so isolating when you’re in the middle of those [painful] moments by yourself. You don’t have anyone who knows what that’s like.”

“[Alaia] was the one who booked the ticket from New York and came to L.A. to see me. She was like, ‘Something’s up. … I sense something,’” she explained at the time. “She saved my life. I think I would have committed suicide, or I would have been dead for sure. I was so close. I could feel it getting to that point. And she saved my life. She pulled me out of it.”

Ireland has also popped up on Alaia’s Instagram feed dozens of times. “Can’t wait to meet my lil hollandaise ????????????? I love you so much already ???♀?,” Alaia captioned photos of herself and her cousin at Ireland’s March 2023 baby shower.
