Photos taken over the weekend during a beach trip to Costa Rica have some moms fired up.
They show the model-mom driving a 4-wheeler with one hand on the handlebar and the other hand on daughter Vivian.
The 1 year-old is strapped onto a baby carrier, but no one is wearing a helmet.
A representative for the model told ABC, "Gisele was on a private beach, driving very, very slowly."
