Brad Pitt reportedly turned down $5 million for a public appearance to spend time with his children.

Photographs later revealed he had joined partner Angelina Jolie and their six children trick-or-treating for Halloween in Los Angeles.

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

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

James Magee, a representative for Global Event Management, said: "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."
