Still-suspended “GMA3” co-host T.J. Holmes had a suspected in-office romp with another junior staffer, a source exclusively tells Page Six.

We’re told “a bunch of rustling” could be heard coming from inside the room and that the woman emerged looking “completely flush” and like “a deer in headlights.”

The still-suspended “GMA3” co-host was previously accused of having sex with a 24-year-old script coordinator at the time, Jasmin Pettaway.

“I do think it was like a, ‘Here’s this good-looking younger girl, and she’s here in my office, let me make a move,’ sort of thing,” the insider adds, describing the situation as “similar” to Pettaway’s.

“They had sex, and I know she was confused afterwards as to what it meant,” the source claimed, calling Holmes “a predator who took full advantage of his position.”

“[Holmes] and Amy are equals,” our insider noted last week, “but if he did have an affair with an underling, that is a definite case for his dismissal.”
