"I know the whole thing is singing to your tune, but I think I'd feel a bit awkward singing to my song," Sheeran said. "I think I'd just want to put on some Biggie… I want to put on something really awkward and dirty, like Biggie's song, 'Big Booty Hoes,' or something like that and just hear James Corden sing along to that."
While Corden didn’t confirm whether he broke out any rap classics in the teaser clip, he did give fans a look at the London week.
“Warning, my accent gets thicker when I’m back home. Even I don’t know what I’m saying,” Corden quipped.
He star-studded guests include Tom Cruise, Emily Blunt, David Beckham, Kit Harington, and Nicole Kidman on, with music from Harry Styles and Kings of Leon. He will also have a Drop the Mic rap battle with Jennifer Hudson.
