He got knocked down, but he got up again! Justin Bieber wasn't about to let a skateboard wipeout stop his fun.

A video obtained by TMZ shows the 'Confident' singer practicing skateboard stunts outside a building in New York City. Even though a crowd of paparazzi and on-lookers were watching, the Biebs seemed unfazed as he jumped over flights of stairs on his board. (No pressure, right?)

As the saying goes, practice makes perfect -- and Bieber is still working on his moves. At one point in the video, he doesn't quite nail the jump and totally wipes out. Ouch! This is a good time to remind viewers to wear helmets. Safety first, guys!

Even after his tumble, Justin proves he's ever the perfectionist, attempting the stunt again. We're impressed with his positive attitude and his perseverance. Way to go, JB!
