Margot Robbie debuted her new cropped hairstyle at the Oscar Awards 2015 last night (22.02.15).

The 'Wolf of Wall Street' star, who is known for her long blonde tresses, stole the limelight when she walked the red carpet at the Dolby Theater in Los Angeles flaunting new modern angled bob.

The 24-year-old actress showed off her ample assets in a black floor-length gown, with a deep plunging neckline, and thin sheer sleeves, which she teamed with a striking Van Cleef & Arpels necklace and a bold red lip to add a spritz of colour to her look.

Speaking to E! host Ryan Seacrest about the standout blue accessory, which features stunning diamonds and sapphires as well as minuscule tasseled detailing, around her neck, she said: ''This necklace right here is worth more than my life, so I better not lose it tonight. It was created for the Duchess of Windsor or something in the 30s, so I'm very lucky to be wearing it.''

The Australian beauty, who shot into the limelight last year when she starred alongside Leonardo Dicaprio, is currently starring in the forthcoming American rom-com movie 'Focus.'

The film, which also stars Will Smith, will hit the big screen on February 27 and will see her portray untrained con artist, Jess.
