Oksana Grigorieva

Mel Gibson's baby mama Oksana Grigorieva was called a gold digger by a former friend, who claims "She was relentless in finding that person who was going to help her career, help her with her son, help her have a good life."

During their custody hearing over their daughter Mel famously offered to pay Oksana $15 million, but instead she turned down the offer and demanded more money. In the end Oksana ended up with a paltry $750,000 and 50/50 split custody with Mel.
