Julia Roberts gives delivery guy 500 bucks to fix air conditioning.

Julia Roberts gave her regular groceries delivery guy $500 to get his air conditioning fixed after learning of his domestic plight.

The generous star gets her groceries delivered to her Malibu home and always tips her regular delivery driver $100 but when he recently revealed the air conditioning in his car had broken, Julia stepped in to help out.

A source told the National Enquirer: "Julia always tips her delivery guy $100 but when he showed up at her house dripping with sweat, she asked if he was ill. The guy apologised and told Julia he'd been sweating because the air conditioning in his car had been broken for days.

"Julia nodded, took her produce and handed the guy his tip, a cheque for $500, telling him 'now get your air conditioning fixed, it's on me.'"

It was previously revealed that Julia - who has three children, twins Hazel and Phinnaeus, seven, and Henry, five, with husband Danny Moder - is reportedly keen to leave Hollywood and set up a base in Hawaii so she can "live off the land" and surf all the time.

A source said: "Julia has been into healthy eating for some time, but she got even more interested in it after deciding to lose the 10 pounds she gained while playing the Evil Queen in 'Mirror, Mirror'.

"She's even considering moving to Hawaii, where her family vacations every year, so they can live off the land, bask in the sun and surf 365 days a year.

"She's turning into a real hippy. She really believes she's much happier and healthier living down on the farm."
