Cara Delevingne modelled some of Rihanna's River Island collection for her fans.

The 21-year-old model showed support for the ''amazing'' clothes from the 'Right Now' hitmaker's Autumn Winter 2013 range by posting a picture herself in a red quilted bomber jacket and black beanie hat from the 80-piece collection.

Accompanying the photo of herself in the Rihanna-designed garments, Cara wrote on Twitter: ''Well done @rihanna for another AMAZING collection for River Island! #keepgoingboo #G4life #goldentouch (sic)''

Rihanna's second collection is available in stores from September 13.

Cara has previously admitted she often asks Rihanna for style advice.

The catwalk star also speaks to veteran supermodel Kate Moss for tips on how to beat troublesome skin.

Cara recently said: ''It only happened during Fashion Week. Which is, of course, the worst time of the year for me to be covered in scabs.

''Kate Moss saw me before the Louis Vuitton show at 3am, when I was being painted by people to cover the scabs. She said, 'This is horrible! Why is this happening? I need to help you.' She got me a doctor that afternoon. Kate gives really good advice.''
