Class is officially in session, with ROLE MODEL as the newest guest star on Celebrity Substitute.

The hit YouTube series, created and hosted by Julian Shapiro-Barnum, first launched last fall and quickly found its charm by sending celebrities into real public school classrooms for a day.

The idea? Have them meet students, connect, and attempt to teach something new. Season one was stacked with names like Andrew Garfield, Florence Pugh, Billie Eilish, Finneas, and Kenan Thompson.

Now, season two is here with an even more jaw-dropping lineup, featuring Reneé Rapp, Gigi Hadid, Malala Yousafzai, Ed Sheeran, Rauw Alejandro, and yes, ROLE MODEL.

“Celebrity Substitute resonates because it blends entertainment with real-world impact,” Julian explained to Variety. “This season delivers even bigger surprises, more heartfelt moments and unforgettable connections between our guest substitutes and the students they inspire.”

For his episode, ROLE MODEL dove into music with the kids, guiding them through a reimagining of his song “Sally, When the Wine Runs Out.” Through their perspective, the track transformed into a joyful anthem only children could dream up: full of heart, energy, and the kind of creativity that makes the series so special.

With its mix of celebrity star power and authentic classroom magic, Celebrity Substitute continues to prove that sometimes the best lessons are the ones no one sees coming.
