After 28 years of marriage and enough drama to last a lifetime, Mel Gibson and wife Robyn announced plans to split in April 2009. That same month, Mel publicly began dating Russian singer Oksana Grigorieva, who was due to have Mel's baby in December (which, coincidentally, was the same month his divorce was finalized). Gibson paid a pretty penny for his infidelities when a judge awarded Robyn half of his assets, nearly $425 million. But was his romance worth it? One year and at least one documented case of domestic violence later, Gibson and Grigorieva went their separate ways in April 2010.
