Billie Eilish interviewed 'Wicked' star Ariana Grande after a screening of the movie, and the musicians hinted that a collaboration could be in their future.

Billie Eilish interviewed Ariana Grande last night after a screening of Wicked at the Directors Guild of America’s theater in Los Angeles. The Q&A, held for Academy and guild members, saw the singers sharing their mutual fandom.
