Minaj appeared Friday on the "Good Morning America" concert series, wearing a loose-fitting halter top that she occasionally had to adjust. As Minaj sang "Where Dem Girls At," some slips made one of her nipples fleetingly visible.
Despite a five-second delay, the slips were seen during the East Coast's live telecast. ABC said they were edited out of Friday's later feeds to other parts of the country.
ABC says in a statement: "We are sorry that this occurred."
