CBS The Material Girl was the latest star to drop her facade on The Late Late Show?s most popular segment. When James Corden traveled to London for his ?Carpool Karaoke? session with Adele, it delivered his show the most-watched late-night clip of the year (136 million views and counting). This week, he went to New York City to try to top that feat with an even bigger legend: Madonna. Corden has karaoke?d with a lot of major stars, but no one with as many hits as Madonna.
