Apparently Sienna Miller is not only the face of Pepe Jeans but she is also going to design her own exclusive range of denim. However, she had better be careful that she isn’t caught wearing a rival’s jeans again, otherwise she might find herself in trouble with Pepe. Another celeb that has supposedly fallen out with her denim partner is Victoria Beckam who according to reports may not be renewing her contract with Rock & Republic.
