With impressive A-level results under her belt, Princess Eugenie was in the mood for fun on a evening out in London last night.

The young royal pulled out all stops for a fancy dress party at Kitts in London's Kensington, charming onlookers with a bat of her rather lustrous pink fake eyelashes as she arrived.

She teamed her lashes with an equally bright top, black miniskirt, silver biker-style jacket and towering peep-toe stilettos.

Before hitting the popular nightclub, the 18-year-old dined at Locanda Locatelli with sister Princess Beatrice and mother Sarah Ferguson.

The trio have just returned from a family holiday in Spain, where they were celebrating Bea's 20th birthday and Eugenie's results.

She officially become the brainiest member of the Royal Family last month by scoring her top grades in art and English literature as well as a B in history of art - just pipping Bea, who despite battling dyslexia, managed an A and two Bs last year.

The Princess' proud parents said in a joint statement: 'We are delighted by Eugenie's achievements. She has worked extremely hard towards these justifiably fantastic results.'

Eugenie, who studied at Marlborough College, the £23,000-a-year boarding school in Wiltshire, plans to take a gap year like her elder sister before going to university.

The fashion-mad teenager could even become the first member of the Royal Family to take an art foundation course.

Her results came weeks after the fun-loving princess - who is sixth in line to the throne - was given a dressing-down by staff at the public school for celebrating the end of her exams by stripped off naked and dancing in the grounds with friends.
