Dayton, Ohio, police were not called, and no charges were filed, according to the report.
Latimer acknowledged the incident in a statement made to KUSA-TV in Denver but denied the dispute was over the club's dress code as TMZ reported.
"It was initially a disagreement (between my uncle and the bouncer) and I was trying to break it up," he told KUSA-TV. "It happened six months ago. It was February 20. It had nothing to do with a dress code. There's not much to say about it. There weren't any cops called. I didn't want trouble so we got out. That's it. It happened six months ago.''
He tweeted a response later Sunday in which he said he has "been through so many positive life changes and have grown so much since Feb. 20, and this situation is in the past."
