Arnold Schwarzenegger and Maria Shriver still haven't divorced - despite splitting up five years ago.

The couple broke up in July 2011 after it emerged the 'Terminator' actor had fathered a son with their housekeeper and although they have both moved on with their lives, neither are keen to make the split official.
According to gossip website TMZ, the pair didn't have a pre-nuptial agreement and had already worked out how to split their $400 million fortune.
And as their children - Katherine, 26, Christina, 24, Patrick, 22, and Christopher, 19 - are all adults, there are no custody issues.
Sources claim that one of the reasons could be that neither wants to walk away from $200 million and other insiders have speculated that super religious Maria, 60, doesn't believe in divorce.
Arnold - who is in a long-term relationship with Heather Milligan, while Maria is dating Matthew Dowd - previously admitted the breakdown of his marriage was his "biggest personal failure" but he is pleased with how things have turned out.
The 68-year-old star said: "It was my biggest personal failure. We all fall at one time or another and this was a major fall. But I had to get up again because only losers stay down, winners get up.
"I had to move forward and say, 'OK, now how do I heal and how can I bring everyone together again? Now I am absolutely delighted with my life."
And the former Governor of California is thankful his estranged wife has worked with him to ensure he still has a good relationship with their kids.
He said: "It has worked out really so well with the help of Maria.
"My kids are a straight 10. I am so proud of them. I'm so in love with them."
