Hosted by KIIS-FM, both Liam and Charlie were a part of this year's star-studded iHeartRadio Jingle Ball presented by Capital One, and during his performance, Liam paid tribute to his buddy by covering a little bit of one of his songs.
Liam kicked off his Jingle Ball performance with his debut solo single "Strip That Down," followed by his Zedd collab "Get Low." Then, he covered a little bit of Charlie's single "Attention," before performing their collaboration "Bedroom Floor."
