New tryst in T.J. story at ABC

SUSPENDED “GMA3” co-host T.J. Holmes has been accused of having another in-office romp with a junior staffer.

A source exclusively tells Page Six the alleged encounter occurred in 2015, the same year a then-married Holmes had another alleged affair with a subordinate, whom he allegedly had sex with in his office.

We have chosen not to disclose the latest woman’s identity at this time, and she has yet to respond to our numerous requests for comment, reports The Post’s Bernie Zilio.

However, our source tells us she was 24 or 25 years old at the time of the alleged hookup, working as an overnight associate producer. Holmes and the staffer, who we’re told is no longer at ABC, were allegedly in his office sometime after 3 a.m. with the door closed. Reps did not comment.

If Holmes does get the boot because of his extramarital activities, ABC brass will be sorry to lose a big rising talent. But Page Six hears that some production staffers will breathe a sigh of relief. Insiders say that while Holmes — who is not looking “very likely” to return to the show after his affair with co-anchor Amy Robach was exposed — got glowing reviews from execs, he’s known to be a pain on set.

“He terrorizes the staff. They hate him. He yells at producers, snaps at people and people don’t want to work with him,” a source told Page Six. Another source described him as “snooty” and “nasty” to staffers, while another insider said he had a reputation for being “a douche . . . long before this scandal erupted.”

“He loves himself . . . He acts like he’s hot s - - t,” they said. “He’s nicer when he’s around the top anchors, but if he’s not with them, he acts like he runs the place and isn’t as nice.”

While his rep didn’t comment, a source close to Holmes called the barbs “a character assassination,” and an insider told us his most recent performance reviews are full of positive comments.

Meanwhile, Robach and Holmes skipped town together yesterday.
