On the day their collab '11 Minutes' dropped.
Yungblud fans got an special treat at his Sydney show last night with US singer Halsey making a surprise appearance.
Halsey joined the UK singer (real name Dominic Harrison) for their track 11 Minutes, which had only dropped that day.
"So this song came out today and I'd like to welcome someone very special to the stage. It's Halsey," said Harrison to a very excited crowd.
The appearance came just hours after the two had thrown a surprise Valentine's Day pop-up event in the city.
