All six   teen stars—Millie Bobby Brown, Finn Wolfhard, Caleb McLaughlin, Gaten Matarazzo, Noah Schnapp, and Sadie Sink—appear in an upcoming episode James Corden’s Carpool Karaoke together. In a preview for the episode, the cast youngsters did not hold back on dipping into various iconic decades prior to their birth, including the 1990s, which saw the reign hip hop as rappers like Notorious B.I.G. dropped hits on hits. Among them was “Big Poppa,” and you better believe these kids tackled that timeless jam.
