Unfortunately for H, while running around on stage during her Hopeless Fountain Kingdom World Tour show in Rhode Island, her boobs fell out of her shirt.
Halsey later apologised to her fans for giving them quite a show, making a joke out of the situation.
"Sorry my boobs came out of my shirt tonight I'm gonna fix it," she wrote after the show. "But also ur welcome I guess u got ur money's worth lmao."
It wasn't the only malfunction of the night either.
Earlier, a fan managed to break Halsey's nail as she reached out to grab her during the show.
Keepin' it real fam.
