Sandra Bullock [1] is one laid-back mom. During an appearance on The Ellen DeGeneres Show on Monday, Sandra talked about taking her 5-year-old son, Louis, back to his hometown of New Orleans for its annual Mardi Gras celebration. After Ellen jokingly asked, "You took him to Mardi Gras? What kind of mother are you?" Sandra replied, "I think a good one. I think if you're gonna learn, you're gonna learn." Ellen then hilariously quipped, "Those are called breasts, son." Sandra, who was named People magazine's most beautiful woman in April, revealed how Louis reacted when he saw some exposed body parts while fetching beads. "He's like, 'Why don't they look like yours?' Well I don't have any." Watch the funny clip above, then check out Sandra's voice work as villain Scarlett Overkill [2] in the new Minions trailer.
