Popstar Rihanna has published pictures revealing her second collection for high street clothing retailer River Island.

Earlier this year, the singer debuted an exclusive collection with the retailer, the first time she had worked with a fashion brand in such a way and showcased the garments during London Fashion Week.

An avid fan of photography app Instagram, Rihanna used her feed to post images to fans of herself working on new designs and fitting models in her latest clothes.

Commenting under one post, the star said: “Me and my better half @adamselman in design mode!!

“We went to #WERK on the upcoming #RihannaForRIVERISLAND Autumn and Winter collections! No really, we took it there!”

Selman is helping the singer fit the model in the snap and has long worked with her on her personal style and Rihanna asked him to take a bow with her at the initial February unveiling, which featured double-top jeans and black dresses.

For this Summer collaboration set to launch next month, Rihanna for River Island will offer floral-print designs as well as a wintry offering, according to The Telegraph.
