Mel Gibson is furious at the large divorce payout his ex-wife received.

While it was previously revealed that Mel gave Robyn half of his estimated $850 million Fortune when they divorced in 2011 after 31 years of marriage, she has also received a huge chunk of his pension.

A source told National Enquirer magazine: ''You'd think someone as wealthy as Mel wouldn't bat an eye at having to hand over half of everything he owns to Robyn especially after the years of hell he put her through with his skirt chasing, drinking and nasty temper tantrums. But he's furious about it.''

However, friends say Mel is lucky Robyn - with whom he has seven children - didn't push for more money.

The source added: ''Mel should count his lucky stars though because Robyn could have been spiteful and looked for even more money than she was awarded.''
