Britain's Princess Beatrice has been seen looking unfashionable after a night of partying with friends. The 18-year-old princess - the daughter of Prince Andrew and ex-wife Sarah Ferguson - had clearly enjoyed herself at London's exclusive Boujis nightclub on Saturday.

Sources claim the redhead - who was without 24-year-old boyfriend, Dave Clark - stumbled out of the club at 3:15 a.m. and was barely able to focus.

Earlier this month, Beatrice was spotted partying in London with Jermaine Jackson.

The royal was seen drinking vodka and dancing with the "Celebrity Big Brother" star at the exclusive Amika club.

A source said: "Beatrice, her boyfriend Dave Clark and a group of about eight pals ordered three huge magnums of Belvedere vodka.

"Their table was right next to one booked by Jermaine Jackson.

"By the end of the night, everybody was firm friends. Jermaine, Beatrice and a few of her pals danced together for ages."
