T.J. Holmes and Amy Robach are getting yanked from hosting “Good Morning America’s” third hour amid a bombshell report that the coworkers were having an affair, according to a source.

The Daily Mail, which first reported the news Monday morning, said Stephanie Ramos and Gio Benitez will host “GMA3” this week while ABC execs figure out how to handle the PR nightmare.

A rep for “GMA3” did not respond to requests for comment.

“There is massive confusion internally,” a source told the Daily Mail. “ABC News executive Kim [Godwin] has taken them off the air while they deal with this internally.”

Over the weekend, Entertainment Tonight published a report that Holmes had an affair with a former “GMA” producer that lasted for a few years before his romance with Robach. 

A source said that this report, in addition to last week’s mess, contributed to Monday’s decision to sideline the co-anchors.

As reported by The Post, ABC News president Godwin and other top execs at ABC were trying to figure out what to do. Last week, they were frantically holed up in “emergency meetings” as videos and photos of the duo canoodling first leaked in the Daily Mail. Sources close to ABC told The Post that Godwin was unaware of the fling.

Although the co-anchors appeared unfazed by news of their romance when they hosted the show on Friday, Page Six reported that Robach and her husband, actor Andrew Shue, were getting a divorce.

It is not clear how Shue or Holmes’s wife, attorney, Marilee Fiebig, learned of the affair, but sources told Page Six that the couples have been separated since August.

On Friday, after “GMA3’s” taping, Robach was seen moving out of the New York City home she once shared with Shue, where she broke her silence on the controversy for the first time.

When asked if she had anything to say, Robach told a reporter from the Daily Mail: “It’s been great. I’ve gotten a lot of support. And, you know, I appreciate everything, and I’m happy to be going to work,” before getting into a black service car.
