Princess Eugenie Celebrates Her 22nd Birthday With A Slimmed Down Figure & Sexier New Look!

Is Princess Eugenie getting a little inspiration from her super skinny cousin-in-law Kate Middleton?

Prince William's beloved cousin, who gained notoriety after she and her sister Princess Beatrice committed a fashion faux pas at the Royal wedding, hit the town in London on Thursday night to celebrate her 22nd birthday, showing off her newly slimmed down figure in a curve-hugging dress.

Wearing a slightly edgier outfit than she is accustomed to, consisting of a tight blue dress, a black leather jacket and heeled booties, the birthday girl grabbed attention as she left London hotspot Hakkasan. 

Eugenie's mother, Sarah Ferguson, Duchess of York, publically struggled with her weight for several years and even became the U.S. spokesperson for Weight Watchers in the 1990's.

Her older sister, Princess Beatrice, has also gained attention over the last few years for losing weight.
