As the saying goes you're only young once and it's important to show off your best assets while you still can – well at least while it's still appropriate.

Emma Watson was spotted with a friend running for a cab on Robertson Boulevard wearing a pair of very short shorts.

The actress, 21, and her girl pal had reportedly just left the Intermix boutique when Watson dashed to catch them a cab, showing off just how trim her legs are.

The Harry Potter starlet wore a pair of black denim jeans shorts and a black vest top.

Sticking to the rules of showing off some skin, the 21-year-old actress also wore a long floral shirt which covered most of her top half.

Keeping the outfit causal, Watson donned a pair of brown work man boots and tied part of her short brunette hair up.

Last month it emerged that Watson had to put her dream of building an eco-friendly clothing empire on hold because her line for ethical label People Tree had failed to sell.

Emma, who has also collaborated with Italian designer Alberta Ferretti in the past, is now concentrating on her studies at Oxford University instead.

A source close to the actress and model said, 'Emma was so disappointed.'

‘But even at knockdown prices, the clothes were still sitting on the shelves. She’s also stalled on plans to do more with Ferretti because she doesn’t have time.’

Watson is currently in Los Angeles filming her new movie The Bling Ring which is about six Hollywood teenagers who burgled celebrities' homes.

The movie is based on a true story which saw stars including Paris Hilton, Orlando Bloom, Megan Fox and Lindsay Lohan all targeted by the gang between October 2008 to about August 2009.

Whilst on set Emma debuted her new look for the role, sporting longer locks after getting hair extensions put in.

The Sofia Coppola project commenced filming in late March and is set for release next year.

It is the second time the story will be portrayed on film, as a Lifetime movie starring Austin Butler and Jennifer Grey was shown on television last year.
