Let it be said that there's not anything Jack Antonoff wouldn't do for his fans ... including riding an upside down roller coaster. 

Over the weekend, before he took the stage at the 2017 Daytime Village presented by Capital One at the iHeartRadio Music Festival, Jack and one of his fans, Kaley, rode the famous New York New York roller coaster. iHeartRadio and Capital One teamed up to make this ride of a lifetime happen; Kaley actually won this once-in-a-lifetime experience because she is a Capital One cardholder.

Ironically enough, Bleachers has a song called "Rollercoaster" from their 2014 debut album Strange Desire -- so you might say things came full circle.

Jack and Kaley hopped in the very front of the roller coaster, which contains loops and goes upside down, not to mention is the world's first coaster to feature a 180-degree "heartline" twist. 

When the ride was over, Jack said, "She had an amazing time. I was just screaming 'holy sh*t,' I don't know. I don't really know what happened. That was way more insane than I thought."  And their photo from the ride itself? It's epic:
