Reunited: Setting the standard for forgive and forget, Maria Shriver joined Arnold Schwarzenegger to celebrate his birthday in Beverly Hills, California, on Wednesday
The former couple were joined by Arnie's children - Katherine, Christina, Patrick and Christopher - for celebratory lunch.
Not joining them it appeared was the Terminator's girlfriend Heather Milligan or Arnie's love child Joseph Baena.
It was revelations that the movie star had fathered Joseph with the family's housekeeper that led to the split between the actor and Maria.

Putting the past in the past: The pair certainly did not seem like there is any bad blood between them as they stuck close to one another as they headed into the hotel
The couple filed for divorce in 2011 but it has never been finalized and as recently as last month Arnold referred to Maria as his wife.

Perhaps trying to remind himself he is 68-years-young rather than 68-years-old, before lunch the action star managed to fit in a workout, a bike ride and motorcycle ride.
Happy to still be pumping iron, the birthday boy posted a video on Twitter to let his fans know how he was marking the day.
In the video he said: 'Thank you everybody for all the birthday wishes, thank you for the emails, calling me, writing me and all those kind of things

'Im having the greatest time - my 68th birthday wow.
'Im in the gym at the moment, I went already on a motorcycle ride and a bicycle ride and now Im going to get a little lunch with my family. So hasta la vista and have a great time, ok.'
Just last month Arnold opened up about his split from wife of 25 years, telling Howard Stern on his SiriusXM radio show: 'I had personal setbacks, but this was, without any doubt, the biggest setback and the biggest failure.

'Without any doubt. Not only failure, but you feel like, ''I'm to blame for it. It was me that screwed up.'' And you can't point the finger at anyone else. So yeah, I was disappointed in it. It's always easy to be smart in hindsight. The thing was how do you make the best of that situation?'
And that was by maintaining a friendship with his ex: 'It has worked out really so well with the help of Maria.'
Talking about what she does for him and his family, the Terminator star revealed how when he was promoting the new film in Germany she organised a surprise for him.

'I walk into the room and I see the room full of balloons... It was from all four kids and from my wife.
'There was a note - ''You're the greatest dad, the greatest man, we love you dad' - Each one sent a card. Each one sent a gift. That's the relationship we have.'
While he said four children he later corrected himself and said his son Joseph was also involved - and he too is a great kid.
'He's terrific and he totally understands the situation. So, it all has worked out... It's a very tough situation for him. It's a very tough situation for my kids. Very tough situation for my family. It was tough for everybody. But it has happened and now we have to figure it out, right?'
