Mel Gibson' private life continues to generate more headlines than his acting and directing career -- most recently for his very public breakup with Russian singer Oksana Grigorieva.

Despite a confidential settlement designed to keep the split out of the headlines, details surfaced last week when Grigorieva apparently named Gibson in a child custody case, which is sealed and will likely remain out of the public domain, the Associated Press reports.
