Brad Pitt turns down UAE offer of $5 million

American celebrity Brad Pitt caused a stir after he failed to show up at a massive event in the United Arab Emirates capital of Abu Dhabi, costing the actor a whopping $5 million, press reports said Saturday.

Pitt was scheduled to make an appearance at the Grand Prix Ball Abu Dhabi on Oct. 31 but he apparently turned down the event to spend the night trick-or-treating for Halloween in Los Angeles with his six children and partner Angelina Jolie.

"He’s spending more time with the family and doing less of these appearances, even though it’s a huge sum of cash," a source told Life and Style magazine.

A spokesperson for the event, which featured performances from singers Beyonce Knowles, Aerosmith and Timbaland, and raised money for clean water charity Fresh2o, admitted Pitt had been expected to attend and was unsure why he had shunned the huge appearance fee.

"We were told he would be attending as the guest of the Tourism Development and Investment Company. But he was a no-show, and nobody seemed to know why," James Magee, a representative for Global Event Management, said.
