As part of a big crew that also included Kristin Bell, Julia Roberts, Neil Patrick Harris and Brandon Flowers–the lead singer of the Killers–Halsey was part of a huge musical number to open Jimmy’s episode. The flashy display was all for a good cause, as the song was about how not giving money to the HIV/AIDS charity (RED) means you’re going to hell.
Halsey stuck around for a second musical performance, too. She and Bono came together for a duet about all the craziness that went down in 2016. The number opened with Halsey admitting she “just can’t even” when it comes to remembering this year.
It’s not the first time Halsey’s been rubbing elbows with A-listers this week.
