Sandra Bullock and Ellen DeGeneres are teaming up against fake endorsement ads.

The duo filed a joint lawsuit in LA Superior Court Wednesday to “expose the Celebrity Endorsement Theft Industry, which … exploits the names, images, likenesses and personas of well-known celebrities who have not authorized or been compensated for such use,” according to the suit obtained by USA TODAY.

The lawsuit claims Bullock and DeGeneres are repeatedly targeted by online scams that use their likeliness to hawk beauty and anti-aging products to unsuspecting customers.

“They are targeted because of their age, their unimpeachable reputation for honesty and having worked hard at maintaining a healthy and youthful look, which con artists believe will attract and dupe unwitting customers into getting bilked by giving up their credit card information,” the lawsuit adds.
