Hilary Duff has shared a video of a "disgusting" paparazzi photographer who was taking photos of the kids at her child's Saturday morning football game.
"Hey, who are you here with?" she says to the man as she approaches, filming on her phone.
"I'm here with me," he replies.
The Lizzie McGuire star goes on to ask whether or not the man knows any of the people on the team. When it becomes clear he doesn't, she asks him to stop taking photos from the sideline.
"I'm asking you to stop taking pictures of our 7-year-old children if you don't know anyone that's here. I'm asking you, human to human, as a mother, if you don't know anyone here can you please stop taking pictures of our children playing football this morning," she says.
The man tells Duff he's just "practicing his photography" and that her "paranoia is unwarranted".
"I'm not here to scare you or anything like that," he adds.
"No, it's just an uncomfortability factor that these are 7-year-old children and you don't have a child here," Duff responds.
"I will just post this to my 15 million followers on Instagram, and let people know how creepy it is that this is what you choose to do on your Saturday morning."
The man then puts his hand over Duff's camera, and the recording ends. As promised, the mother-of-two did share the clip online.
"Go 'practice' your photography on ADULTS! Creep!" she captioned the video.
"Laws need to change! This is stalking minors! Disgusting!"
Duff has already received an outpouring of support from fellow celebrities, including Busy Phillips and Emmy Rossum, who both agreed laws around photographing children needed to be tougher.
