The 18-year-old singer rocked out onstage in Times Square, performing three of his recent hits -- "As Long As You Love Me," "Beauty And a Beat," and an acoustic version of "Boyfriend" -- in the freezing New York weather, but decided to show a little swag by lifting his shirt at one point during his set.

As his fans went into a frenzy, Bieber calmly grinned out at the crowd, showing off his six-pack abs, as well as his boxers and a tiny tattoo on his left hip.

Earlier in the day, the "Never Say Never" singer shared his latest ink, a giant set of praying hands next to roses on his left leg.

"New tat," he captioned the photo.

The young singer has a wealth of other tattoos, many of them religious. He has a portrait of Jesus wearing a crown of thorns on his leg, as well as the word "Yeshua" ("Jesus" in Hebrew) on his ribcage.
