Paris Hilton was paid $140,000 to party at a London nightclub for less than two hours.

The hotel heiress arrived at Mahiki, in Mayfair, with her Good Charlotte rocker boyfriend Benji Madden at 1.20 a.m. on Tuesday, April 15.

Paris - who promised 'Mahiki Madness' on the invitations to her special evening - performed a steamy dance for Benji before the pair left at around 3 a.m.

A source said: "Paris and Benji were all over each other and, at one point, she gave him an impromptu lap dance. Everyone was staring, which only seemed to spur Paris on."

The club paid tribute to Paris by making her a special version of their $200 Treasure Chest cocktail, a potent mixture of champagne and spirits. The drink - which was kept on ice until she arrived - was decorated with flowers and had her name stamped on the side.

Before she left, Paris took to the dance floor and gyrated to her single 'Stars Are Blind'.
