Could our day possibly get any better?!

One of our loyal X17 readers just sent us these snaps of Justin Bieber performing at the Calvin Klein even in Hong Kong, and we love that the pop star whipped off his shirt and showed off his smokin' hot abs! Fans thought the Biebs was merely making a promotional appearance at the event, but much to the delight of the crowd, he performed a few songs as well. Guess he's getting ready to get back on the road!

Bieber's manager Scooter Braun tweeted, “Yeah @justinbieber is killin it at he #calvinkleinlive event in Hong Kong. Out of no where he took a request and is playing #onetime!” The 21-year-old superstar sang “Boyfriend," "One Time," and “Beauty and a Beat,” among other hits ... Check out clips from his performance below!
