Rihanna just announced that she will be working with River Island on a clothing line to be released in Spring 2013!

“I’ve been wanting to design my own collection for some time. River Island is the perfect partner for me to collaborate with and working with a British, family run business also really appealed to me,” Rihanna said in a statement. “I find London really inspiring and River Island loves to have fun with clothes. I’m looking forward to working with them and creating something really special.”
