Lady GaGa's Lollapalooza set cost $250,000.

Organisers of the three-day Chicago music event were so desperate to keep the `Poker Face' hitmaker happy they shelled out $100,000 on a giant stage and an additional $150,000 on her production requirements.

Event organiser Perry Farrell told MTV: "We spent like $100,000 to give her a giant stage. We spent close to $150,000 to house the production she's gonna do. And I say yeah, let's do it."

The 24-year-old 'Alejandro' singer is known for her expensive stage shows and spent £52,000 on a bathtub for her performance of 'Bad Romance' on UK TV show `The X Factor' last year.

It has also been reported that Gaga made a loss during her North American leg of her 'Monster Ball' tour and overspent by £2 million of her sold out tour.

Other acts performing at the Lollapalooza festival - which runs from August 6-8 - include The Strokes, Soundgarden, Green Day and Arcade Fire.

The event runs from the 6-8th August in Chicago.
