Leona Lewis has become the new Brand Activist for The Body Shop.

The 'Bleeding Love' singer - who is a strict vegetarian and a campaigner for animals rights - has teamed up with the ethical beauty retailer to help raise awareness for their collections and causes.

She said: ''I'm passionate about beauty and I'm all about animal rights. As a result, I'm really conscious of where the products that I use come from. The Body Shop sells cruelty free, ethical products containing amazing Community Fair Trade ingredients. The collaboration is a natural fit!''

As part of the partnership, one of Leona's first activities is to help The Body Shop and NGO Cruelty Free International in their joint, global campaign to end animal testing for cosmetics forever, building on the EU ban on animal testing for cosmetics which comes into effect on March 11th this year.

Leona has also put her name to an exclusive cruelty-free make-up and fragrance collection, the Limited Edition Collection by Leona Lewis.

The collection - which features 100 per cent vegetarian cosmetics in fashion-forward shades - uses a floral deer motif, celebrating the fact that The Body Shop was one of the first beauty brands to use cruelty-free, man-made musk instead of musk derived from the musk deer.

The Limited Edition Collection by Leona Lewis is available at selected stores from March 25.

To celebrate the partnership, Leona will also be holding an exclusive gig for fans which will be live streamed on March 26.
