With stylish stars like Angelina Jolie dressing kids in her clothes, it’s no wonder that more celebrities want to line up with Stella McCartney.

Pop singer Leona Lewis has her eyes aimed at such a collaboration, specifically an eco-friendly one.

“Leona and Stella got on famously. They are both vegetarians, don’t wear leather and are huge animal lovers. The [fashion] line would be very animal-friendly,” reveals an anonymous source.

The news comes after the pair were spotted being awfully chatty at a charity event, Children In Need, in London. Although McCartney has designed costumes for the film Sky Captain and the World of Tomorrow, this team-up would be her first with a celebrity, despite having previous done lines for Adidas and H&M.
