Lesson: Know your partner’s nutty side

Actor Mel Gibson began appearing publicly with Russian musician Oksana Grigorieva even before his divorce from his wife of 26 years was filed. However, their relationship only lasted less than a year and culminated in restraining orders against both parties and charges of domestic violence. A scandal involving alleged taped abuse followed Gibson in the summer of 2010. In 2011, their relationship officially ended with them being awarded joint custody of their daughter, Lucia.
