Pharrell Williams has been criticised for selling a crocodile skin Louis Vuitton handbag.

The animal rights organisation PETA released an open letter obtained by TMZ on Tuesday which slammed the Happy hitmaker for releasing a crocodile skin handbag with luxury fashion brand.

"When you were made men's creative director of Louis Vuitton, we hoped animals would get lucky and that you would choose vegan fabrics, which are the preference of today's ethical and environmentally conscious consumers," PETA Senior VP Lisa Lange wrote. "But we aren't happy to note your newest design, the Millionaire Speedy bag, which is crafted from crocodile skin, because when it comes to animals being used for fashion, it isn't beautiful - it's abuse."

The bright yellow crocodile skin handbag has been priced at $1 million (£813,845).

"A PETA Asia investigation found workers at LVMH's suppliers cutting live crocodiles' necks open and ramming metal rods down their spines while they were still conscious. Another investigation revealed that workers at facilities supplying LVMH struck pythons repeatedly on the head, suspending them in the air, inflating their bodies with water, and disembowelling them - even as they moved about," the letter continued. "You'd want to bring along nose plugs and high boots to wade through foetid, waste-filled water."

It concluded, "If we go to an indoor tank, also bring a flashlight, because you won't see daylight. There are no blurred lines here.

"Killing wildlife for a bag isn't cool - it's cold. Are you up for this trip?"

Lisa also recently called out Offset for buying three crocodile Birkin bags for his wife Cardi B's birthday.

Pharrell, who was appointed Louis Vuitton's Men's Creative Director earlier this year, has not yet responded to the letter.
