Eagle-eyed viewers caught a glimpse of a picture of the prince with a penis drawn on his head today morning.
The image flashed up during a music video for a song titled "I Could Have Married Kate" by comedy singing group Barbershopera.
Several viewers tweeted a screen-grab of the image, shown during the BBC's breakfast television program.
The BBC said "the material was provided by Barbershopera but we failed to spot the offending material within it. We apologize for this.
