Wearing casual sweatpants, a turquoise puffer vest and sunglasses, Paltrow helped her kids sell small glasses of lemonade for $1 and large classes for $2.
"It was super cute and a lot of the neighborhood kids were stopping by," a witness told Us Weekly. "People were very surprised to see Gwyneth standing out on the corner like any normal mom. She was very sweet to the kids who came up, calling them 'sir' or 'ma'am' and pouring them drinks."
Ben Affleck and Jennifer Garner's daughters, Violet and Seraphina, set up a lemonade stand back in 2011, selling cups of the sweet drink for 50 cents each. Affleck even talked a few members of the paparazzi into buying some.
