Officials at animal rights group People for the Ethical Treatment of Animals (Peta) have sent actress Anne Hathaway their vegan-living guide in the hope of persuading the Oscar winner to have another go at a meat and dairy-free diet.

The Les Miserables star tells the new issue of Harper's Bazaar veganism left her feeling weak and unhealthy, and she recently changed her eating habits, but the Peta bosses are refusing to give up on the actress and they've sent her cookbooks and diet guides in a bid to make her rethink a diet overhaul.

Colleen O'Brien, Peta's senior director of communications, tells Wenn, "Sometimes when people quit smoking, their bodies buck at the change, even though it's a healthy one, and they start smoking again. But, in the end, most people make the switch a permanent one.

"Peta knows Anne Hathaway to be kind and to care deeply about animals. She may have received some bad advice, so we're here to help her with healthy recipes and copies of our extremely popular vegan starter kit, which makes going vegan the right way very easy.

"We'll be sending her a vegan gift basket in the hope that she'll consider how humane, healthy, fortifying, and delicious vegan meals can be."
