An eight-minute film made for the star's nuptials with Jessica Biel reportedly opened with a slide reading: "Greetings from your Hollywood friends who just couldn't make it."
And this was followed by clips of homeless people wishing Justin and Jessica all the best in their marriage.
But now JT has taken to his official website to protest his innocence, writing that he couldn't "fight the urge to clarify thoughts and feelings" on "a very upsetting portrayal of the people closest to [me]".
He continued: "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.
"I grew up with a family and community that instilled ideals in me like hard work, honesty and empathy... Growing up in Tennessee, I was always taught that we as people, no matter what your race, sex, or stature may be, are equal.
"As it pertains to this silly, unsavoury 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."
And the singer-turned-movie star also defended his pals, who are reported to have made the short film.
"My friends are good people," he continued. "This was clearly a lapse in judgement which I'm sure no-one who is reading this is exempt from. But, I don't believe it was made to be insensitive.
"More so, I think it was made as a joke on me not having that many friends attending my own wedding (which IS kind of funny if you think about it)."
And he insisted that the film wasn't shown at his wedding, contrary to the reports.
He said: "Like many silly rumours that I have been made aware of about the week: It was NOT shown at my wedding.
"I think we can all agree that it was distasteful, even though that was not its intention. Once again, in the world that we live in where everyone thinks that they know everything, I want to be very clear... I am NOT defending the video. I agree with the overall consensus.
"I want to say that, on behalf of my friends, family, and associative knuckleheads, I am deeply sorry to anyone who was offended by the video."
