A funny video has emerged of a little girl inventing a freestyle song to tell her parents how much she likes Oreo cookies.<br /><br />The footage, captured last month at a home in St. Louis, MO,USA, shows 3-year-old Vivienne performing to convince her parents to give her her favourite cookies. <br /><br />''Vivienne, wanted Oreos before bedtime, and my wife and I told her no,'' the father later wrote online.<br /><br />''She proceeded to sing us this freestyle song about how she liked Oreos.''<br /><br />''She still didn't get any Oreos that night,'' he added.
