While details are currently scarce, the songstress announced July 16 that her capsule collection will launch at the high street retailer for 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," said the singer in a release.

"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."

Like other UK high street retailers such as Topshop and Miss Selfridge, River Island -- which ships internationally -- is known for its affordable, catwalk-inspired statement pieces which are strong on embellishments and prints.

Rihanna, meanwhile, is known for her edgy red carpet looks and daring on-stage attire.

"I've always loved fashion. Fashion has shaped me into the artist I am today," she recently explained in a video to promote her upcoming UK television show Styled To Rock.

Set to premiere this August on UK screens, the reality show tracks unknown designers as they compete for the chance to dress her at London's Wireless music festival.
