*Serena Williams has signed on as the newest ambassador for Allstate Foundation Purple Purse, the insurance company’s decade-old initiative to provide financial empowerment to domestic abuse victims.

The pregnant tennis star takes over for Kerry Washington as ambassador of the organization, which says it has helped about one million women escape abusive relationships through a mix of financial education and job training.

In explaining her decision to sign on, Williams told Mic.com, “Not a lot of people really know about financial abuse. It’s an invisible but also really devastating form of domestic abuse that traps victims in these harmful relationships.”

One reason financial abuse is so prevalent, Williams said, is because it takes many different — sometimes subtle — forms. An abuser might contact their partner’s employer, for example, and undermine their ability to stay on the job. Or the abuser might take out and use credit cards in their partner’s name.

“If a woman’s credit is ruined, she can’t get an apartment,” Williams pointed out. “Most of the time when people leave abusive relationships, they have this awful debt and that can take years and years to recover, especially if they have kids.”

Williams’s announcement on Thursday (June 22) came with a newly-released hidden-camera style video by Purple Purse — showing ride-sharing passengers who get into a car and discover a purse that has been left behind. Soon, a phone inside the purse begins ringing, and the passengers then see a series of alarming texts that indicate an abusive relationship.

The video’s message? If you see something, say something, says Vicky Dinges, Allstate senior vice president for corporate responsibility, who heads the project. She tells mic.com: “It’s not okay to look away … People should ask themselves, what would I do if I were faced with this situation?”
