Christina Aguilera hits a high note with Melissa McCarthy on 'Carpool Karaoke'

Christina Aguilera grabbed a ride on The Late Late Show Carpool Karaoke Primetime Special. And while she and James Corden made beautiful music together, they made funnier music when Melissa McCarthy joined them. The segment started with Corden and Aguilera riding around Los Angeles in a Range Rover. The first song they sang was "Fighter." They then spent a little time talking about Aguilera's Disney years. While Aguilera and Corden were singing "Dirrty," Melissa McCarthy magically appeared in the back seat. McCarthy claimed, "I have been here the entire time!" And she explained, "I've been laying down... in back, I ride on the floor." So all three continued to sing the song. Even though everyone in the car can sing, only Christina is a true diva. So she gave the other two a crash course in warming up diva style. And while they did pretty well, Melissa and James realized they could never be Christina good. If you want to see more of Aguilera and McCarthy together, you can checkout their new film Life of the Party. The Late Late Show with James Corden airs weeknights at 12:37 a.m. on CBS.
