We're not sure why Bill Clinton would take a call from Justin Bieber, but a source "close to the situation" tells E! that's exactly what happened. Bieber called to apologize for a recently released video of Bieber peeing into a restaurant bucket and then shouting, "F--- Bill Clinton" at a picture of the former president. Clinton was apparently really chill about the whole thing, the source says, basically telling Bieber that "if that is the worst thing you have ever done, all is well." Bieber tweeted about the conversation yesterday: "@billclinton thanks for taking the time to talk Mr. President. Your words meant alot. #greatguy." (More Justin Bieber stories.)
