The star also shared a video that captured her intimate birthday festivities. In the Instagram Reel clip, the family celebrated with an outdoor bash seemingly thrown at the Honest Company offices, complete with a bevy of pink-and-gold decorations, a full food spread, birthday hats and delicious cupcakes.

Alba recently opened up to PEOPLE for the annual Beautiful Issue about how her fashion sense has changed over the years, saying her "style is more fun now than it was when I was younger."

"I probably used to stick to kind of one aesthetic," she explained. "Now I don't care. I can just change it up and I have no attachment to one vibe or another. Sometimes it's much more preppy. Sometimes it's much more boho, vintage, whatever."

Throughout the past year though, the star has definitely had one go-to aesthetic: comfy casual. Alba joked she has been living in "anything that could probably be mistaken for pajamas" throughout the COVID-19 pandemic.

"I actually set up like a little desk area in my closet. I just don't really have to get out of sweats most of the time, or lounge pants," the L.A.'s Finest star said, adding that recently she has enjoyed getting dressed up in "real clothes" and going "back out into the world."

For Romper's March cover story, Alba opened up about her decision to take a back seat from acting after the birth of her first child, Honor, who will turn 13 this summer.

"That's really what motivated me," the Sin City star said of not taking her own health for granted, when it came to being around for her kids. "My motivation was not like, 'Am I ever going to get hired again?' Frankly, I was at the top of my career."

After Honor's birth, Alba realized she "couldn't go back to what I was doing before and be authentic. I just couldn't. I just didn't care about it anymore the same way. It was something bigger."

"I felt like if I was going to, I guess, sort of get this platform, what can I do with it that could be meaningful and make a difference?" she continued. "That reality just felt so real when I became a mom for the first time."
