Amy Robach didn’t expect her alleged affair with T.J. Holmes to “blow up into a scandal,” a new report claims.

The “GMA3” personality, whose shocking romance with her co-host catapulted the pair into the news cycle last November, feels like “collateral damage,” a source told the US Sun.

“She had no idea the scope of T.J.’s alleged past office romances,” the insider added, referencing Holmes’ alleged dalliances with an intern 13 years his junior and an ABC producer.

“She certainly did not foresee that their relationship was going to cause major upheaval — outside of her own marriage.”

Robach, 49, and Holmes, 45, were taken off the air shortly after news broke of the scandal. An internal investigation remains ongoing at ABC.

The US Sun’s source believes the inquest “will look into Amy’s past to try to find some scandal,” noting, “But fortunately for her, she is fairly well-behaved.”

However, a source tells Page Six that Robach was not “blindsided” as the report claims — at least by Holmes’ relationship with producer Natasha Singh. The insider claims he was “up front” with her regarding their former relations.

Page Six has reached out to reps for Robach and Holmes for comment.

The new report comes just one week after a source claimed to DailyMail.com that Holmes had a months-long affair in 2015 with then-24-year-old Jasmin Pettaway — while married tohis now-estranged wife, Marilee Fiebig.

“He was a predator who took full advantage of his position, and he was reckless,” claimed the source, who reportedly knew the script coordinator well at the time.

“It was Jasmin’s first real job in television, and it was a big deal for her. She was looking for a mentor, and she reached out to several people. T.J. was someone who was responsive, but he absolutely abused the position of trust.”

The insider alleged that the two had sex, claiming Pettaway was “confused afterwards” as to what it all meant. The source further claimed that Holmes’ behavior was part of a pattern of “incredibly reckless” conduct on his part.

Amid all the recent media attention, Holmes and Robach’s jobs at “GMA3” are believed to be on thechopping block.

The pair were swiftly taken off the air after their relationship came to light.

“They have not been terminated yet, but I don’t expect T.J. to be on again,” an insider told Page Six last week, noting that both parties have lawyered up amid negotiations.

“They do want Amy to stay and be a part of things there, but likely not on ‘GMA3.’”

Amid the scandal, Holmes and Robach have also split from their respective spouses, Fiebig and Andrew Shue.

Holmesfiled for divorce from Fiebig in December 2022. Meanwhile, Robach had already had been close tofinalizing her split from her actor husbandby the time the affair hit the headlines.
