Listen to Arcade Fire on iHeartRadio

The man behind Arcade Fire's Pope Francis mask at Coachella is finally showing his face. 

It turns out it was "Breaking Bad" star Aaron Paul who donned the giant paper-mache head this past weekend and took the stage during the indie rockers' headlining set at the Indio, California festival. 

Celebrity guests sneaking into the band's show this way is turning into an almost regular feature.  At last month's Lollapalooza Chile, Strokes frontman Julian Casablancas hid in Win Butler's mask for a while before Win playfully kicked him off the stage. 

And fans can look forward to another secret celebrity cameo this weekend when Arcade Fire returns for Coachella Round Two!
