However, Reid's comment appeared to confuse Johnson who simply asked: "Who's Lorraine?"
Of course, former GMB presenter Piers Morgan shared his thoughts on the PM's gaffe on his new programme Piers Morgan Uncensoredon TalkTV and had some strong words for Johnson.
"We all know Lorraine Kelly. I think he knows Lorraine Kelly, he just didn’t know what on earth was going on in that whole interview," he said, discussing the matter with Tom Newton-Dunn.
"I thought Susanna skewered him beautifully and he just lost his way and lost his mind, as he does so often."
"He could probably survive partygate, he can't survive insulting Lorraine Kelly, it's over for him."\n\nPiers Morgan tells Tom Newton Dunn that Boris Johnson waited until he left Good Morning Britain before going back for an interview.\n\n@tnewtondunn | @piersmorgan | @reallorrainepic.twitter.com/GxttTANR9B
Boris will be heading back to the fridge after that. \nWell done @susannareid100 - the Elsie line of attack was lethally effective in exposing his Government\u2019s failure to properly help our most vulnerable people amid soaring inflation.
