Miley Cyrus, Katy Perry, and more join James Corden for 'Christmas Carpool Karaoke'

The Late Late Show With James Corden shared a special "Christmas Carpool Karaoke" featuring some very special guests. Popstars like Miley Cyrus, Katy Perry, and Bruno Mars were part of the festive fun. The stars sang "Santa Claus Is Coming Town." With the exception of Reggie Watts, all the performances appeared to have been shot throughout the past year. But it wasn't all singing, as Corden took a moment to wish his guests a "Happy Christmas." Corden must have wanted Harry Styles to have a particularly happy Christmas because he locked lips with the singer in a friendly manner. The whole performance was filled with holiday cheer and fun moments.
