Princess Beatrice drinks William and Harry under the table

It seems anything that her older cousins can do, Princess Beatrice can do better.

When it comes to partying, Prince William and Harry might have set an example running up a £5,000 drinks bill at Soho nightclub Mahiki at the weekend.

But Princess Beatrice appeared more than equal to the task.

The 18-year-old was seen stumbling out of Royal favourite nightspot, Boujis at 3.15am yesterday, looking more than a little bleary-eyed after a night of heavy partying.

Barely able to focus and with her dark make-up smudged around the eyes, she appeared to reel sideways as she staggered outside, sending her coiffured auburn hair flying.

But she quickly recovered, hastily clambering into her waiting carriage under the watchful eye of her minders.

Wearing an eye-catching aqua and black satin dress, accessorised with a sequined blue bow handbag and a black alice band, the elder daughter of Andrew and Sarah, Duke and Duchess of York, enjoyed a night out with friends at the West London nightclub.

Onlookers described how she appeared to be in great spirits, although slightly unstable on her feet.
