Mel and Robyn Gibson
Rob ShuterMel Gibson has made some huge mistakes lately but nothing compares to the biggest mistake of his life: letting Robyn Gibson, his wife of nearly 30 years, go. Now the troubled star will do whatever it takes to win her back including moving his entire family back home to Australia.

"Meeting Oksana Grigorieva and leaving his wife was the biggest mistake of Mel's life," a friend of the actor tells me. "Robyn and the seven children they have together are heartbroken to see what has happened to him. Seeing the man they know as a husband and father being portrayed as a monster is very painful and not the man they thought they knew. However, neither is the man who would walk about from them for a younger Russian gold digger."
