London, Apr 14 : Princess Eugenie, daughter of Prince Andrew and Fergie, was seen dancing on tables after she downed beer with ketchup for an Easter bet with pals during a wild night in Thailand.

The 19-year-old Royal partied at the trendy Lizard Lounge club near Surin Beach in Phuket, where she is on a gap-year jaunt.

"The Princess was with a couple of girls and a guy. One of her friends squirted some ketchup into a glass of beer and challenged her to drink it. They all fell about laughing as Eugenie swigged it," the Sun quoted an onlooker as saying.

It is believed that Eugenie, the sixth in line to the throne, is staying at a 10 pounds-a-night backpacker hostel after flying out economy class.

And while the princess let her hair down, her two Met police protection officers-who apparently flew down via business class-sipped mineral water at the bar. (ANI)
