Rihanna is known for her sense of style, whether she's going glam on the red carpet, working a casual look or wowing audiences with her outrageous stage costumes.
Her first capsule collection will go on sale in the stores from spring 2013, reported Daily Mail.
Rumours were rife that the 24-year-old was going to work with River Island after she was spotted visiting the chain's head office in London.
"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," she said.
The clothes and accessories in the popstar's line have not yet been finalised but River Island chief executive Ben Lewis said the range will reflect her 'street to chic' style.
"We are thrilled to be collaborating with Rihanna and to be the first fashion brand to work with her in this way. Rihanna is a style icon, from street to chic she enjoys her fashion. As soon as we started to work together we knew this was a perfect fit.
"Rihanna will be designing the collection and we will be sharing our fashion experience with her to develop a range her fans will love," Lewis said.
