Street-to-chic: Rihanna is in London to meet with River Island bosses to discuss her fashion range for the high street store

Rihanna's range for River Island is likely to be a little less controversial than her choice of flight wear.

But the company's CEO Ben Lewis hopes she'll be able to capture her own 'street-to-chich' style.

Speaking after the deal was signed in July he said: '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.'

And the star herself promises the clothes - which will go on sale from sprint 2013 - will be inspired by her love of London.

She said: '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.'
