Bystanders captured photos and video of the incident, which included Baldwin's wife Hilaria Thomas, who just gave birth on Friday, wagging her finger sternly at someone off-camera, presumably 60-year-old Adao.
In another photo, she was seen crying about the incident, which occurred during the pair's first public outing since the birth of Carmen Gabriela, who was not there at the time.
A notorious hothead, especially when it comes to paparazzi, Baldwin, 55, pinned the photographer after confronting him about the photos.
“We are here on earth to do good unto others. What the others are here for, I have no idea. -- WH Auden,” Thomas tweeted after the fracas.
