The Grammy Award-winning singer has bared all to raise awareness about the abuse of tigers in circuses.
Photographed crouched inside a cage and wearing nothing but striped bodypaint, Chilli is urging fans to 'Boycott the Circus' in the ad.
Peta officials have learned that many big cats used by circuses are beaten into submission, and when they're not performing, they are locked away in cramped, filthy cages.
Tiger lover Chilli says, "There's so much cruelty behind the scenes, which is a something that a lot of people don't get to see. They're (circus trainers) being mean to them to make them do this trick... and I think that everybody needs to be aware of what's really going on."
Asked why she decided to strip off for the provocative new campaign, the Waterfalls singer adds, "If you can raise awareness to something that's important, such as this, then you should. I know for a fact that I would never want to be in a cage."
She joins a growing list of celebrities, including Alec Baldwin, Jada Pinkett Smith, Olivia Munn and Edie Falco, who have teamed up with Peta to speak out against circuses that use animals.
