The New York Post reports that Trump sent a black "girdle-like outfit" she wore in the film "Exit to Eden" to her cohost Barbara Walters on Monday.
The get-up was bought at a charity auction by a fan who delivered it to Trump, the newspaper reports.
"I sent it to Barbara to hang in her office because I didn't want it in mine. It was funny, except that it was really gross. It's disgusting," Trump told the New York Post. "I feel sorry for (Rosie's) wife. It can't be pleasant."
The newspaper reports that on Monday's show, O'Donnell asked her cohosts, "You want to hear what a 61-year-old businessman did today? He sent Barbara …"
Walters interrupted O'Donnell and said, "This was sent for me, it was not sent to you … I really do not want to stir up the whole Donald Trump thing again."
Walters later told the newspaper that she isn't going down that road again. "I am supportive of my friend and colleague Rosie," she said, "but I have no desire to continue a feud with Donald Trump."
The feud began in December when O'Donnell railed Trump after he gave Miss USA, Tara Conner, a second chance when she was busted for underage drinking.
"He annoys me on a multitude of levels. He's the moral authority? Left the first wife, had an affair; left the second wife, had an affair; had kids both times, but he's the moral compass for 20-year-olds in America?" O'Donnell said at the time.
Trump told David Letterman last month that Walters didn't speak the truth throughout the feud.
"She was trying to protect Rosie. She just said things that weren't so and therefore I sort of wrote her off my list. She's off the list," Trump said.
