Seems that Robin Thicke’s major effort with his “Get Her Back” campaign and his album “Paula” failed to bring her back to him. According to TMZ Thicke’s wife Paula Patton has finally filed for divorce after nine years of marriage. The filing comes seven months after the couples separation citing “irreconcilable differences,” with Patton filing for joint custody of her and Robins four-year-old son, Julian. This is a little surprising since Robin Thick has been struggling with various substances but he also says he is trying to stay clean.
