Discussing the impact that social media sites like Twitter and the internet have had on people in the public eye, singer Lamar said "a bad picture lasts a long time these days".
He talked about images of famous people published in the media, including the large-framed US politician Chris Christie whose size may hamper his ambitions, and how Eric Pickles MP uses his image for humour.
Panellist Jacqui Smith said she had no sympathy for men and their images, as she spoke about how people look at men in the public eye - and why some politicians may have shaved off their beard.
Michael Portillo looked at the image of Harold Wilson, the pipe-smoking former prime minister.
