Bell got a bunch of stars, from Jennifer Aniston to Jennifer Lawrence, who agreed to decline interviews with TV and text outlets that use paparazzi photos or video of children that were taken without their parents' consent. Then she met with entertainment media executives and told them either agree to her No Kids Policy or celebs will stay away.
Now, through upcoming media interviews and meetings with "mommy bloggers," Bell is taking her cause direct to consumers, asking them to consider the circumstances around the starry images that beckon at grocery checkstands.
"There is no way for a child to wrap their head around the fact that they are a cog in this machine," Bell said in a recent interview. "All they experience is the predatory sense of being hunted."
And the actress would sooner quit the business than subject her 11-month-old daughter, Lincoln, to such a media scrum.
"I like being an actress very much," she said, "but I love being a mother and it is a very clear decision which one I would choose."
Bell and her famous colleagues can't outright refuse interviews as they leverage the power of celebrity to stomp out invasive imagery of kids; contracts typically obligate them to promote their movies and shows. But they can be picky about which outlets they'll work with.
Star-driven shows and magazines such as "Entertainment Tonight" and Us Weekly, which rely on images from freelance photographers and independent photo agencies to help illustrate their stories, say it's easy to support Bell's effort. But their interpretations of compliance vary.
"Entertainment Tonight" executive producer Brad Bessey said he would not use paparazzi-generated photos of celebrity kids under any circumstances, while Us Weekly editor-in-chief Mike Steele might consider such images in cases of breaking news involving the children.
Steele said the new policy hasn't affected editorial operations at the magazine, other than requiring an extra step to get consent from celebrity parents before publishing images of their kids. Some agree and some don't, he said.
Like other entertainment news outlets, Us Weekly also uses social media for pictures of star children, which are inherently approved when posted by their celebrity parent.
So with varying sources for kid photos — approved or not — how does Bell monitor compliance? She and her publicist are doing it themselves, they say, and it isn't easy.
Tuan, a freelance paparazzo who shoots for the Phamous Photo agency, said he hasn't seen any change in demand for his pictures, which sometimes include unauthorized images of celebrity kids.
"We have these long lenses and keep our distance. We let them enjoy their weekend," Tuan said. "The kids generally don't know what's going on."
Two major celebrity-photo agencies, Splash News and x17, also continue to distribute paparazzi images of children. Both declined to be interviewed for this story.
