Gone but not forgotten! The BBC received a deluge of backlash after airing an image of Prince William with a not-so-flattering accessory on his forehead during their morning program BBC Breakfast on Thursday, August 1.

The morning news program aired a video by musical theater group Barbershopera titled "I Could Have Married Kate" at one point during their show as part of a segment promoting their appearance on the show.

Viewers quickly jumped to criticize the show, however, after editors "failed to spot" an image of Prince William with a penis drawn on his forehead that flashed on the screen for several seconds.

"Yup, that's a penis on Prince William's head," one viewer tweeted. "Outrageous."

The new father (wife Kate Middleton gave birth to their baby son Prince George on Monday, July 22) also sported glasses, a silly moustache and goatee, and a few missing teeth courtesy of someone's black marker.

"This image was shown fleetingly within a comedy promotional video for Barbershopera, a humerous barbershop group, who were appearing later on in the program," a BBC spokeswoman said in a statement.

"The material was provided by Barbershopera but we failed to spot the offending material within it," she continued. "We apologize for this."
