Justin Bieber's taking his shirt -- again. But we ain't mad at it!

The 20-year-old superstar showed off his chiseled abs and rockin' pecs for V Magazine's Music Issue. In the mag, the Canadian said, "I want to show my creativity to the world."

By "creativity" we think the Biebs may have meant "abs" -- at least judging from these pics and the recent Calvin Klein ad campaign!

In the shoot, which were photographed by famed designer Karl Lagerfeld, the half-naked star smoldered as he talked about his future.

"I'm still young. I still have so many personal and professional goals I want to achieve," Justin told V.

"I want to keep creating music for my fans. One day I hope to make strides into movies and fashion as well."

Well we will be looking forward to seeing that -- as well as more pics of his abs!
