“Am I supposed to be afraid of Riz ‘cause he raps? His lyrics lack depth just like when he acts. You might recognize him from some TV shows, or not at all if you don’t pay for HBO,” Corden quipped.

He also added, “This is a blood bath. It’s not a fair fight. It’s like you were overbooked on the United Air flight,” referencing the recent headlines surrounding a United Airlines passenger who was dragged off a flight.

The Rogue One star fought back, rapping, “Yeah, I did do Star Wars. I bet that made you mad. Too bad they weren’t trying to cast Jabba the Hut’s dad. Yeah, I had Lena’s baby. It was fun. I was on Girls, but you never touched one… You’re not an emcee, you begged me to let you down gently. I wouldn’t stop this war if Kendall Jenner brought out Pepsis.”

Corden also mocked Ahmed’s Coachella performance to which the rapper replied, “I saw you at Coachella, you were the big white tent!”
