Following the coverage of the US inauguration, her co-host Piers Morgan was quick to point the social media meltdown as he read out some tweets. "Yesterday, this huge historic day… But it was nothing to do with the inauguration," he said on Thursday.
"It was Susanna Reid's cleavage, which appears to have made a huge, huge impact on the nation. Susanna heats up breakfast - I hadn't really noticed, because obviously I don't objectify you in the workplace so I hadn't noticed." Susanna quipped: "Women shouldn't have boobs at breakfast - they're for later on!"

Piers then remarked: "I'm very relieved on behalf of the nation that you've decided to put them away today because we can’t cope with that kind of heat at 6:43 in the morning." To which, Susanna replied: "You're right, I’ve completely covered up."
Despite the backlash, many viewers were quick to applaud Susanna's choice of outfit with one writing: "Susanna is a very beautiful lady x she looked lovely in her dress."

Another stated: "Susanna looked absolutely lovely in her dress. Some say it was a racy outfit. Susanna is HOT for her age. Wear what suits you. It pulls the viewers in as well. Keep looking good." A third post read: "If you’ve got it, flaunt it! I thought you looked stunning, as always."
