Cheryl Cole & Katy Perry To Star In Rihanna's TV Show
The singers are just some of the celebrity guests on Styled To Rock…
Each week the show will see one of the celebrities give the promising designers a task to make them a costume.
The star will then choose their favourite of all the designs.
It was already known that Cheryl would be appearing on the Sky Living show after Henry Holland posted an Instagram pic of himself with Nicola and Chezza on his Twitter page saying: "I've joined the band!"
Nicola Roberts spoke to Look Magazine this week about working with Rihanna and said that she "couldn't have been more lovely".
Styled To Rock starts on Sky Living on August 14.
