VIDEO : Selena Gomez Joins James Corden For 'Carpool Karaoke'

James Corden's newest Carpool Karaoke segment featured pop star Selena Gomez and a handful of unexpected props. As they sang along to Taylor Swift's "Shake it Off," the pair took shots of ginger, rode a rollercoaster, and ordered McDonalds. Ginger is said to be a natural remedy for sore throats, benefitting singers and performers with stressful schedules.
