Everyone was so busy checking out Justin Bieber's bum when he lost his pants onstage earlier this week that it took a while for people to notice that he also got a new tattoo!

To be fair, the Biebs has so many tats already -- some 20 and counting -- that it's hard to keep them all straight. But Radar Online to the rescue! It spotted the fresh ink in photos of the singer while he was performing onstage in Singapore on Monday (Sept. 23).

The tat, which is on his right shoulder, is a Bible verse from Psalm 119:105. It states, "Your word is a lamp for my feet, a light on my path." Justin, a devout believer, has other Christian-themed tattoos in his collection: On his calf, he has Jesus wearing a crown of thorns and praying hands, and on his torso, he has the name "Yeshua" ("Jesus" in Hebrew).

What tattoo will Biebs get next? We've got a few ideas!
