The Sports Illustrated swimsuit model also Instagrammed the amazing white-and-pink cookies her lucky guests got to devour. The sweet treats featured shapes like crowns, baby carriages, onesies and bottles.
Teigen and Legend's friend, Command PR owner Simon Huck, shared photos from inside the fête as well, including a peek at the fancy table decor...
...as well as an Instagram of himself, Teigen and two friends, which Huck jokingly captioned, "Making America Great Again."
Teigen wore white for the occasion, dressing up in a skin-tight tank dress, which she paired with a long beige-and-white coat and strappy nude heels. She showed off the outfit as she carried her pup into the shower.
Even though Teigen and Legend are excited for their baby girl's arrival, the mom-to-be admitted to ET last week that they still haven't decided on a name for their little one.
"We have a running list on our phones," Teigen said during the Miami stop of the press tour for her book, Cravings. "But we change it everyday. It's why I don't have a tattoo. There's nothing I like for more than 10 minutes."
