Ray was debating whether parents should be allowed to take their children work with co-host Susanna Reid when he said: "You have presented with some babies over the years, haven't you? They stormed out and threw a tantrum."
Morgan tweeted in response: "Hmmm. Given how Mr Ray has helped destroy GMB’s ratings since I left, if I were him I’d probably avoid mocking the guy who took them to record heights…."

Ray, 47, is co-hosting the breakfast show as one of a number of rotating guest presenters to join Reid since Morgan's departure.
His presenting style has provoked a mixed response among GMB viewers.
Some were offended by his line of questioning to TV presenter Reggie Yates about his new film Pirates, about a group of teenagers trying to celebrate New Year's Eve 1999.
Ray said: "I love the fact that you literally, you're breaking down the stereotypes, haven't you? We, you know, we think of a movie about Black kids and it's sort of gangs and it's gangsters and it's, you know, drugs and all of that.
"But there's none of that really. It's a coming of age story."
Yates, 38, who wrote and directed the film raised his eyebrows, replying: "Yeah, so it's a coming of age story fuelled by joy more than anything, and I think we've had more than our fair share of trauma filled issue-based movies."

The former Top Of The Pops presenter said the film is a celebration of UK Garage music.
Asked his favourite Garage track, Yates named DJ Luck & MC Neat’s A Little Bit of Luck.
But as GMB producers struggled to find the song, they played Shanks & Bigfoot's Sweet Light Chocolate instead.
As he danced and sang along Ray asked if the track featured in the film. When Yates said no, Ray told him to consider it for a sequel.
One viewer tweeted: "Jesus this is painful, someone finish this interview quick!! I feel for Reggie Yates here."
Another agreed: "Lol this interview with Reggie Yates was hard to watch #GMB."
And one viewer observed: "Anyone else find the discussion about UK garage on @GMB with Reggie Yates, you can see on his face he isn’t impressed with the disrespect. It’s the same story time and time again, can’t pronounce something from black culture so they make fun of it."
