The always delightful, bare-chested Justin Bieber put the ass back in class last night when he nearly caused a stripper to faint with just a simple touch.

According to TMZ and a Texas stripper who goes by @1real_diamond on Twitter, the Biebs hit up VLive, a "raunchy" joint where "girls do things that leave marks."

Always the gentleman, Biebs apparently took off his own clothing in an effort to make the ladies feel comfortable before he began the ass touching. According to another unnamed stripper who is definitely not an intern writing copy for TMZ, he also made it rain on the ladies — and in a nonsensical aside that TMZ does not explain whatsoever, "based on the videos we saw ... apparently so did her co-worker."
