The mom-to-be spent time with McConaughey pal Sandra Bullock on Tuesday, taking their little ones – Louis and Vida, both 2½ – to watch the Warren Easton Charter High School’s marching band and drill team perform.
“Camila seemed happy to attend the event with her kids. The kids all go along and seemed to have fun,” a photographer tells PEOPLE. “It was a bit windy and all the kids wore their hoodies. They looked very cute. Sandra and Camila chatted and both looked happy.”
Warren Easton (the oldest public high school in Louisiana) is special to Bullock, who “adopted” it in 2007 and has donated “hundreds of thousands of dollars” to help pay for an on-campus health clinic, college scholarships and band uniforms, her rep told PEOPLE in 2011.
Meanwhile, the next day, the moms got together for a second play date at the Carousel Gardens Amusement Park.
