Gisele Bündchen showed off her postbaby bikini body in Hawaii today. She sported a black two-piece while hanging poolside with friends, and later dried off after taking a dip in the water. Gisele kicked off her tropical getaway with her husband, Tom Brady, son Benjamin, and daughter Vivian on Wednesday when the family of four landed on the island. Gisele carried Vivian in her arms, marking the first time that the 2-month-old was photographed out since her birth announcement in December. Just this morning, Gisele shared a personal snap of Vivian on Facebook with the caption, "Love is everything!!! Happy friday, much love to all."
