James Corden recently housed Will Smith in the new spinoff series Carpool Karaoke, and as he told E! News at the show’s premiere, he was totally smitten.

“Are you kidding? I’m constantly Google Earthing myself and imagining if I could tell my 12-year-old self that this is my life. His head would explode,” he gushed. “Are you joking? I never even thought I’d get to meet Will Smith, let alone have emails and texts with him and stuff like that.”

He continued: “I’m not in all of the show, I’ve done the first one with Will and the very last one with LeBron James. The LeBron episode, we start in an empty Staples Center and we end in the biggest ending we could think of for a series like this. And in between, there’s just all of these incredible people. And what’s amazing is that everybody came to it with the same attitude which is ‘This is going to be fun and we’re going to try and have  great time.’ It’s mind-blowing when I look at the list of people that are in the show.”

The rest of the 20-episode season is going to pair up celebs for carpools of their own. Some will make sense, while others are surprises (like Billy Eichner and Metallica!). Alicia Keys, John Legend, Ariana Grande, Seth MacFarlane, Chelsea Handler, Blake Shelton, Michael Strahan, John Cena, Jeff Gordon, and Shaquille O’Neal will also join.
