On December 6, both Halsey and BTS attended an annual music festival '2019 iHeartRadio Jingle Ball' that took place in Los Angeles, the United States.
On this day, Halsey and BTS performed their collaborative track 'Boy With Luv' together.

When they were standing around together, BTS handed a thick black case that had "Halsey" written in sparkly pink.
BTS members urged Halsey to open it, and when she did, she screamed in happiness after seeing a gold sparkly customized microphone in it.

She continued, "BTS gifted me my own sparkly microphone. It was really thoughtful of them. It was amazing that I got to use it as well."

The seven members of BTS went over to grab one huge Christmas stocking each from the back.
RM commented, "Wow, this is the biggest sock I've ever seen in my life!"
JIN also said with his voice full of excitement, "Whoa! It's very very very cute."
After going through the things inside the stocking, V held up a candle and told Halsey, "This is my favorite candle."
Meanwhile, Halsey and SUGA recently collaborated for the second time for a song titled 'SUGA's Interlude'.
