Gisele Bündchen spent a well-deserved afternoon off with her man Joaquim Valente and her 12-year-old daughter ... the first time she's been spotted since giving birth!
The super model was photographed in a cheetah-print top and a black skirt in Miami Saturday ... donning a pair of sunglasses to keep sun out of her eyes.
Bündchen's hair is tied back ... and, she's clearly in full-relaxation mode -- laying out on the deck of a yacht with her daughter Vivian and getting a tan.
