Khloe Kardashian is helping to save the world's tiger population by giving fans the chance to join her on a shopping spree.

The Keeping Up With The Kardashians star has teamed up with celebrity charity website Prizeo to raise money for the World Wildlife Fund's tiger conservation campaign.

She is offering to accompany one lucky donor on a shopping trip in Los Angeles in a bid to boost funds. All those who donate will be entered into a raffle for the prize.

Kardashian says, "I'm so pleased to be working with Prizeo on a fundraising concept that allows my fans to get involved... When we all work together we have the greatest impact, and wild tigers desperately need our help. My fans have always been wonderfully supportive, and through this campaign I hope to inspire as much action as possible to help save these magnificent animals."
