Princess Eugenie

Princess Eugenie

Britain's Princess Eugenie went on a night out with her mother Sarah Ferguson on Tuesday (13.11.12).

The 22-year-old royal partied with boyfriend Jack Brooksbank and her mum at Lou Lou's private members club in London, and stayed out until the early hours of the morning.

Eugenie - who usually keeps a low-profile - and Sarah even opted for coordinating mini-dresses and coats.

In recent weeks Eugenie has enjoyed a number of nights out, including a trip to the world premier of 'Skyfall' at London's Royal Albert Hall and a night out with her cousin Prince Harry's ex-girlfriend Chelsy Davy.

Recently, Sarah, 52, said she always wanted her daughters Eugenie and Beatrice to smile when they are in public because "grumpy princesses" are not of any interest to the public.

She said: "If you're on the public pavement, smile - because nobody wants to see a grumpy princess.'

"And I say, 'The minute you're out of the front door, you're in public, and if you don't want to go out, don't go out. And if you do go out you've got to be nice and realise how lucky you are.' "
