The latest Palin family drama: Track Palin, oldest son of Sarah and Todd, has filed for divorce. For those of you not up to speed on the Palin brood, Track is the one who has been accused of drug problems more than once, and he's also the one who provided his parents with their second grandchild just a couple months after getting married. That child, daughter Kyla, is now 1. Track and wife Britta filed the divorce documents jointly, indicating property and custody issues have already been settled, TMZ reports. Track will keep a $30,000 bank account; Britta gets $4,000 worth of jewelry and physical custody of their daughter.
