On Friday, she came out as a Backstreet Boys fan.
Schumer shared a hilarious video of herself jamming to the classic '90s boy band while on a boat in Central Europe.
"#roadmanager is fired up for Switzerland," the Trainwreck star joked in a caption for the Instagram video.
Last week Schumer shared a photo of her high school girlfriends in a human pyramid, featuring one very recognizable new BFF – Jennifer Lawrence.
"She's the coolest chick you'll ever meet," Schumer told Jon Stewart earlier in the week. "She's the best hang, she was like one of the gang."
