Hip-hop mogul Pharrell Williams is adding jewellery designer to his extensive resume after impressing Louis Vuitton designer Marc Jacobs with his ideas.

After working with timepiece manufacturers, Jacob The Jeweller, on watch designs, Williams decided it was time to get his hands on some bling.

He says, "I told Marc that I wanted to do jewellery for LV. I got my designs and ideas together. I did a lot of research."

Williams is convinced his new Louis Vuitton jewellery line will be as successful as all his other ventures: "It's going to be major - super regal."
