It's the singer's first high street collaboration...
River Island has announced that Rihanna is to design a clothing line for the store.
Rihanna said of the collaboration: "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.
"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."
River Island added: "We're so pleased to announce an exciting collaboration with Rihanna. Yep, she will be designing her first clothing range exclusively for River Island.
"We're all huge fans of Rihanna's style here at River Island so you can imagine how flattered we were when she approached us about working together and bringing our fashion experience to her range."
This isn't the first time Rihanna has dabbled in fashion. The We Found Love singer has previously designed capsule collections for Giorgio Armani and her fashion designer reality show, Styled To Rock, is due to hit our TV screens in August.
RiRi's collection will be in River Island stores in Spring 2013.
