This NASCAR legend and his wife, Brooke, split in 2002 after seven years of marriage. While she was the one who filed the paperwork and received a reported $15.3 million settlement when the split was finalized, she kept one significant memento from their marriage -- Gordon's last name. In 2010, the #24 driver got dragged into a custody dispute when his ex bestowed his last name onto a child she had with another man. Gordon is now married to model Ingrid Vandebosch, with whom he has two children.
