James Corden is normally down for whatever. But when he drove Selena Gomez around on the latest edition of "Carpool Karaoke," he didn't realize what was in store. Commenting on the fact that he worked too much, Selena suggested a little detour on the way to work. And the two ended up on a roller coaster while singing "Come and Get It." Then if that wasn't already making James' stomach turn, he partook in one of her daily morning routines—a whole ginger shot—which immediately made the late night host look like he was about to get sick. But before he had a chance to really show how awful that shot was, the two stopped by a McDonald's drive-thru and freaked out some of the fast food chain's employees. Despite the surprises Selena threw at James, the two had a blast singing along to her hits including "Hands to Myself," "Kill Em With Kindness," "Love You Like a Love Song" and Taylor Swift's "Shake It Off."
