And yes, Ari sang Céline Dion.
Titanic is many things: a perennial classic, a movie that launched everyone's Leo crush, and instant tearjerker. And now, thanks to Ariana Grande and James Corden, it's a musical you didn't even realize you wanted.
The duo transformed the tragic tale into an elaborate musical medley on The Late Late Show last night, running through a total of 13 songs and concluding with a duet of Céline Dion's "My Heart Will Go On" from the original soundtrack.
The pop star (whose new album Sweetener drops Friday) and late night host hit all of our fave moments from the movie, selecting a few surprising but hilarious songs. They started with Styx's "Come Sail Away," and included "Just Dance" by Lady Gaga and NSYNC's "Bye Bye Bye" (we'll let you guess for which part).
Check out the five-minute mini-musical—which was shot all in one take, btw—below.
