Gisele Bündchen's new necklace is more than a stylish accessory - it appears to be a heartfelt tribute to her family and a potential hint at her new baby boy's name. The model, 45, was seen wearing a yellow gold necklace with the letters "J, B, V and A," in a photo posted alongside her sister Patricia via Instagram on Tuesday, January 13, just over a month after tying the knot with husband Joaquim Valente.
