Pregnant Gisele Bündchen was glowing and showing during her Costa Rican escape with BF Joaquim Valente ... proudly flaunting her growing baby bump.
The Brazilian supermodel wasn’t flying solo -- she had her two kids with ex Tom Brady, 12-year-old Vivian and 14-year-old Benjamin, soaking up the Costa Rican vibes for a dreamy family day out with her man.
Gisele rocked a cropped white top, showing off her bump as the family cruised around, all smiles and good vibes.
