Kanye West `jealous` of Pharrell Williams?

Los Angeles: Rapper Kanye West is said to be jealous of Pharrell Williams after reports emerged that the latter is close to signing a deal with Adidas. Adidas is the same sportswear brand that West has been commissioned to design a clothing range for, reports contactmusic.com. "They are competitive in both music and fashion, Kanye always watches what Pharrell does. He thinks having a similar artist working on their own brand for Adidas will make his collection less special," a source told The Sun newspaper. West, 36, signed a deal with Adidas in December, 2013, after a spat with Nike, over royalties for his exclusive collection of Air Yeezy sneakers, which resulted in the end of his business relationship with the sportswear brand.
