The 20-year-old model wowed the crowds as she arrived in a low cut lace gown last night. Dressed in the black floor length Burberry dress which featured lace detailing on the arms and back along with a plunging neckline, Cara proved her model credentials by posing up a storm on the red carpet. She accessorised her Cannes look with an array of eye catching silver jewellery while she wore her long brown hair down in loose curls. All in all, Cara looked right at home in the French city. The model also seemed to brush off the recent controversy which has surrounded her over the past few weeks. Two days ago, Cara proudly showed off her first ever tattoo of a lion on her index finger to her fans on Instagram. Thanking Rihanna for her tattoo artist recommendation, she captioned the picture: "My first tattoo!! Lions rule! Thank you so much @bangbangnyc @badgalriri." Unfortunately, Twitter users were more interested by what was under her nail as oppose to the tattoo itself. The picture shows a suspicious green substance lodged under the model’s nail, leading to speculation from Twitter users as to what it could be. One user wrote: "Look at that weed under her nails,” while another said: "Nice weed in your nail." Cara caused further controversy earlier this month when she was photographed dropping a suspicious looking bag filled with white powder.
