Earlier in that week, Alba made a big business move by taking her The Honest Company public Wednesday with an IPO that values the brand at $1.44 billion. The mom of three rang the opening bell at the Nasdaq MarketSite in Times Square to celebrate her clean lifestyle brand's initial public offering, with her children at her side.

Alba compared the near-decade of work and the grit it took to take Honest public to pregnancy, jokingly calling it "a nine-year gestation period."

"Every single moment has mattered so much and I learned so much along the way," she told PEOPLE at the time. "You know when you're pregnant and every month when your baby goes from a walnut and then eventually it's like the size of a grapefruit, then it becomes a melon. Every stage feels so different and new. Once you actually have the baby, you're like, the real work has now started. That's how I feel today."
