Kim Kardashian hit Las Vegas this weekend for her second round of birthday celebrations – she’s not one to do things by halves! The star looked knockout in a white figure-hugging mini dress that showed off every inch of those famous Kardashian curves. She accessorised with white nails and plenty of bling. Kim celebrated with her husband Kris Humphries and her family, who presented her with a surprise birthday cake during the party. Of course this wasn’t just any old cake but a cake in the shape of a sports car, hey, what do you expect? This is Kim Kardashian we’re talking about!
