Justin Timberlake posted an open letter on his website about the controversial video that was reportedly shown at his wedding to Jessica Biel. The video, which showcased footage of homeless Los Angeles people, had an opening slide that read, "Greetings from your Hollywood friends who just couldn't make it."  In an October 26th post, he wrote, "I'd like to start off by saying that I don't live my life making fun of people... Especially, those who are less fortunate or those in need... As it pertains to this silly, unsavory video that was made as a joke and not in any way in mockery: I had no knowledge of its existence. I had absolutely ZERO contribution to it."  Justin continues, "My friends are good people. This was clearly a lapse in judgment which I'm sure no-one who is reading this is exempt from. But, I don't believe it was made to be insensitive... It was NOT shown at my wedding... I do understand the reaction and, by association, I am holding myself accountable. Thank you for giving me the opportunity to share my thoughts. P.S. You can bet your a** that I'm having my friend do at least 100 hours of community service... Boom."
