MEL & ROBYN

They spent nearly 30 years together. But on April 13, Robyn Moore sought a divorce from husband Mel Gibson. Since the couple have no prenup, the split could be the costliest in Hollywood history. The actor, who maintains that he and his wife split three years before the formal filing, is expecting a child with his Russian musician girlfriend, Oksana Grigorieva.
