Rihanna spent £15,000 on alcohol in just three hours
The `Rude Boy` singer headed to London nightclub Mahiki after playing a sold-out show at The 02 Arena and treated her huge entourage to champagne, vodka and Jagermeister - a German herb liqueur.
One fellow reveller said: "She turned up with a massive entourage of about 70 people. She ordered thousands of pounds worth of alcohol, including Krug champagne, huge bottles of Grey Goose vodka and trays of Jager-bombs."
The 22-year-old pop star had her own private dancefloor and partied until the early hours, at one point dancing to one of her own songs.
A source told the Daily Star newspaper: "She had a section of the dancefloor cornered off just for her and when the DJ played her song `Rude Boy` she started gyrating with a bunch of men."
The Barbados-born beauty stayed at the club with her entourage until around 4.30am before heading back to her hotel.
A source said: "When she left she was clutching a half-drunk bottle of Mount Gay rum. She took it into her car, saying it was a souvenir as it?s made in her home country, Barbados."
