Jennifer Garner and Halle Berry testified before the Assembly Judiciary Committee at the California State Capitol on Tuesday to support a new law that would impose stricter penalties on photographers who tail celebrities and their children.

Garner, who has three kids with Ben Affleck, held back tears as she described one particular stalker.

She told the committee members, "Being stalked has been hard for me, but it is beyond what a child should have to endure. I am an actress but I am a mom first. My children aren't actors or celebrities. They're just kids like your kids or anyone else's and, just like you want to protect your children, I want to protect mine... They're beautiful and sweet and innocent, and I don't want a gang of shouting, arguing, lawbreaking photographers who camp out everywhere we are all day every day to continue traumatising my kids."

Berry revealed that one paparazzo had the audacity to tell her five-year-old daughter Nahla that she may never be reunited with her dad Gabriel Aubry as her parents engaged in a bitter custody battle.

Berry explained, "(The photographer) said, 'How do you feel, Nahla? You may not see your father again. How do you feel about that?' They say curse words and call me names, all trying to provoke some sort of response to sell a photograph."

The actress also revealed how her daughter responded to the invasive questions.  "(She asked), 'Why did they say that to me, mommy? What does that mean? Who are these men and why are they following us?' We aren't just whiny celebrities... We're moms who are just trying to protect our children."

The SB606 proposal would ban paparazzo from taking photos of a child without the permission of a legal guardian. The bill is headed to the Appropriations Committee for review.
