Cara Delevingne and Rita Ora are planning a joint clothing line.

The showbiz pals are hoping to go into business together by pitching a quirky and contemporary clothing collection to Topshop mogul Philip Green, thanks to their connection with his daughter Chloe Green.

A source told The Sun newspaper: ''Rita and Cara have been talking about the idea for weeks now. Cara has great fashion industry contacts and Rita loves her clothes and keeps up with trends.

''They think a line could compete with those released by Victoria Beckham and Kate Moss. Rita's become increasingly matey with Chloe Green and has mentioned the idea to her in the hope that she might help get it to her dad, Topshop boss Philip.''

The fashion-mad duo are rarely seen without one other these days and rarely stray from the best-dressed lists. While in-demand model Cara opts for head-to-toe glamour at showbiz events, she and ''wifey'' Rita are best known for their casual off-duty style.

The rumours come after the inseparable pair spent the evening together at the Glamour Women of the Year Awards in London on Tuesday (04.05.13), where 'R.I.P' singer Rita scooped the Best Artist gong.

Cara shared a snap of herself posing with her best bud on Twitter, adding the caption: ''So proud ritaora Well done!!! (sic)''.
