AceShowbiz - Benjamin Rein is growing up right before our eyes. While spending time together with his mother during a day out, the son of supermodel Gisele Bundchen and retired professional football player Tom Brady towered over Gisele.

On Thursday, August 8, Benjamin was out and about with Gisele in Miami. In a series of pictures that made their rounds online, it could be seen that the mother and son duo were strolling around the city in Florida. They were joined by their beloved dog, whose leash was held by Gisele.

Benjamin and Gisele were photographed walking close next to each other and seemingly having a fun conversation. They were spotted looking at one another with Ben, who was taller than his mother, giggling. They looked in good spirits during the walk as they were smiling from ear-to-ear in some of the photos.

At one point, Gisele let the black-furred dog play, taking the black leash off the German Shepherd. She was pictured throwing a yellow ball, prompting the dog to run and catch the toy. In the meantime, Ben, who was holding a bottle of drink in one of his hands, was watching the smart dog play.

For the relaxing stroll on the sunny day, Benjamin went with a comfy ensemble. The 14-year-old sported a short-sleeved black tee that came with colorful graphics on its front side. He also wore a pair of matching shorts, matching flip flops and a wrist watch.

In contrast, his mother Gisele opted to wear a white T-shirt that featured a high neck design. The former Victoria's Secret Angel, whose long blonde hair was let loose, completed the look with a pair of light blue denim shorts that had rip details. She also donned a white baseball hat and a pair of brown sandals.

Benjamin is Gisele's eldest child. Aside from Ben, the Brazilian blonde beauty and cookbook author is a mother to her 11-year-old daughter Vivian, whom she shares with her former husband Tom. She also took care of Tom's 16-year-old son Jack, whom he has with actress Bridget Moynahan.
