Will Smith and the cast of Aladdin perform James Corden's "Crosswalk the Musical"

The Late Late Show host appeared in blue face to play the Genie. But Smith, who was joined by co-stars Naomi Scott and Mena Massoud, took over the role. "I'm the Genie, man, you can't do Aladdin without the Genie," Smith said. "James, listen I understand how you're feeling. I'mma keep it real, you are more like Abu."
