Gisele Bündchen put her growing belly on display at a recent charity event ... showing off her new baby bump for the very first time!!
The supermodel rocked a sleek black dress for the Lotus House Gala's 20th anniversary celebration in Miami ... and sure enough, her bun in the oven was the main accessory catching everyone's eye.
As we reported last month, Gisele is expecting her first child with jiu-jitsu instructor Joaquim Valente .
