Gisele Bündchen and Tom Brady attended Gisele’s twin sister Patricia‘s wedding in Brazil on Saturday – and their 3-month-old son Benjamin Rein cut a dashing figure, sporting a mini tuxedo for the occasion.

Patricia, who is Gisele’s fraternal twin, married Rodrigo Pereira at the Laurentia Vineyard outside Porto Alegre.

Gisele, 29, served as maid of honor – leaving Brady, 32, in charge of the diaper bag.

This is baby Benjamin’s first trip abroad, and the first chance for most of Gisele’s family to meet him.
