Last month, Lorraine, 59, appeared in an episode of the ITV soap in which she got shot in the leg with an arrow by Gail Platt.
Many viewers branded the cameo hilarious and Lorraine's pal Piers decided to crack a joke about her acting.
During Monday's Good Morning Britain, Piers jokingly told Lorraine she was wooden in the scene.
The show rolled a clip of Gail, who is played by Helen Worth, accusing Lorraine of "milking it" after firing an arrow into her thigh.
Piers joked: "What an allegation, seems like she's becoming a serial killers of TV presenters on ITV Daytime."
Lorraine said: "I know, she's going through us all. Susanna [Reid], just watch out, that's all I'm saying."
Piers asked: "How's your leg after the appalling incident?" to which Lorraine replied: "It's fine. Did you see my acting? What was it like!"
Piers quipped: "I've got to say, I didn't think the Woodentops were still working."
I've got to say, I didn't think the Woodentops were still working.
Laughing, Lorraine said: "I think that's insulting to the Woodentops. It was great fun though, and they were all so lovely up there."
Piers then made Corrie an offer to have him in the soap.
He said: "I want to be in the Rovers Return as a kind of smoothy, mid-50s love interest for Kym Marsh, I've already said this.
"It hasn't happened yet but I'm available. I could be Britain's answer to Clooney."
Lorraine received a mixed reaction to her soap performance.
Some viewers weren't impressed by the cameo and called the acting "cringeworthy".
One person said: "God Lorraine Kelly's acting was bad #Corrie," while another added: "Lorraine Kelly sketch on #Corrie embarrassingly bad. #coronationstreet #lorrainekelly."
A third wrote: "I don’t think I’ve ever actually seen anything quite as bad as Lorraine Kelly’s acting on #Corrie."
