Yesterday a video circulated showing Justin Bieber urinating in a New York City restaurant's mop bucket, like the entitled adult-child pop star that he is. (Turns out this all went down inside Artichoke Basille's Pizza.) He followed up his bodily fluid performance with an encore: a giant "f*ck you" to former President Bill Clinton, whose photo was hanging on the wall of the establishment. While Bieber didn't apologize to the restaurant staff who had to clean up his mess, he did take a moment to apologize to the bold face name.

He announced on his Twitter account that he chatted with the former President, Tweeting at him: "thanks for taking the time to talk Mr. President. Your words meant alot. #greatguy." Clinton Hashtag Great Guy didn't respond to the Tweet, but a source told Extra the two had a "great conversation" and Clinton "told the pop star to be conscious of the friends he keeps and to focus on the good work he is doing." And an "insider" told E! Online that the former Prez told the pop star: "If that is the worst thing you have ever done, all is well."

Bieber also upset people recently by touching the Stanley Cup, or something.

ICYMI, here's that video again:
