Princess EugeniePrincess Eugenie, the younger sister of Princess Beatrice, has been given a severe telling off after being caught naked and drunk in the grounds of her private school.

Eighteen year old Eugenie has been a boarder at £23,000-a-year Marlborough College, Wiltshire, for the past five years but has now been barred from staying at the school at weekends after the incident earlier this month.

A school source told the Sun that a senior staff member was woken by shrieks from the lawns and found the princess, along with a dozen other students, dancing naked in the moonlight: “It’s the talk of the college.

“The girls had been drinking, possibly in a local pub, and decided to let their hair down. For some reason they stripped off and started prancing about.

“It was light-hearted and they were sort of frolicking like nymphs. But they got too noisy and staff discovered them. They had to quickly pick up their clothes and hot-foot it inside.

“She and the others were told they had to go home and only return to take their exams. There were not enough staff on Saturdays and Sundays to supervise them, and they were told they couldn’t be trusted to behave.”

Eugenie, who is sixth in line to the throne, is taking A-levels in art, history of art and English.
