Justin gave an acoustic concert for his Aussie fans and sang "Boyfriend", "Die In Your Arms," "As Long As You Love Me," an "Fall".
He's been spending the past few days in Sydney, Australia, and his fans are going crazy.
He's done interviews, fan meetings, and of course performed live in concert! Justin even took time to visit a children's hospital to spend time with sick fans.
Justin's girlfriend Selena Gomez has been there to support him, but as he's been so busy she's been exploring Sydney and going shopping with his best friend Alfredo Flores.
Ah, and one update about Justin's album. Remember when he and Taylor Swift revealed they were working on a song together? Well, they initially thought it was going to come out on Believe, but it just didn't fit on the album. So it'll get released later - and it's already got the Selena Gomez stamp of approval.
Here's Justin's performance of "As Long As You Love Me" - it's so great!
