AceShowbiz - Hilary Duff has called for California law to be changed after she confronted a man photographing kids at her seven-year-old son's soccer game on Saturday, February 22.

The actress and singer posted a video of herself confronting the man, whom she believed to be paparazzi, on the sideline of her son Luca's game on Instagram.

Reflecting on the incident in an Instagram Story video on Monday, the 32-year-old mother of two explained that other parents had complained as they were "uncomfortable" with the man's actions and that she had contacted the police, explaining that officers were "pretty dismissive" of her as the game was taking place in a public park.

Calling for a law change, the "Younger" star added, "It's just extremely strange and inappropriate and creepy to have a man photographing our seven-year-old children and that to be completely legal. Like, if a parent is asking for it to stop, the laws should be changed for you to not be able to photograph that person."

"If those kids are a subject of your 'photography' practice, over and over and over again for minutes or half hour, however long it was, and you ask someone to please stop that, you should have that right. And we really need to work on changing that law."

The star also admitted that thinking back, she is unsure whether the man, who offered to show her identification, was a paparazzo, as she did not recognise him as one of the snappers she usually sees following her.

After posting the initial video, she received messages of support from other famous mums including Busy Philipps and Nikki Reed.
