That wouldn't have been good for Gigi's intricate lace Zuhair Murad Couture gown.
But while accepting her award at Glamour's Women of the Year ceremony on Monday night, the supermodel shared that she doesn't always feel like "Gigi Hadid, global supermodel". She finished the look with a high ponytail and a coordinating metallic hair accessory. "Not only lovely on the outside, but totally stunning - most importantly - on the inside, she understands in order to be the best you have to think like you are the best, you have to work the hardest, and you have to make sacrifices".
Serena Williams presented her with the award on the night - admitting she would only ever leave her newborn for Gigi.
While boyfriend Zayn, who she has just celebrated two years with, wasn't there, her mum Yolanda and brother Anwar joined her and Bella.
After collecting her award from tennis ace Serena Williams, Gigi said: "I think my biggest responsibility, standing here, is to all the young women who are watching".
For her first post-baby red carpet appearance, she chose the exact same Versace dress worn by Hadid on the Milan Fashion Week runway.
Gigi added, "So tonight, I celebrate all of you being honored and celebrate women all over the world. And I want you to imagine the effect you have on the world", Williams said to Hadid, according to People. "And she's authentically herself".
