Donald Trump has unleashed a secret weapon in his feud with Rosie O’Donnell - a gigantic black undergarment she wore in the movie “Exit to Eden,” which Trump sent to Barbara Walters on Monday to hang on the office wall at “The View.”

The girdle-like outfit - variously described as “a bustier” and “a giant pair of panties” - was bought at a charity auction by a fan, who then had the relic framed under glass and delivered to Trump.

“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 Page Six. “I feel sorry for [Rosie’s] wife. It can’t be pleasant.”

O’Donnell played the police detective partner of Dan Aykroyd in the 1994 comedy described by Leonard Maltin as a “strange cinematic catastrophe.” The two cops go undercover at a sado-masochistic fantasy camp, which required O’Donnell to wear the bustier with garters and stockings while brandishing a whip.

On “The View” on Monday, O’Donnell asked Walters, Joy Behar and Elizabeth Haselbeck: “You want to hear what a 61-year-old businessman did today? He sent Barbara . . .”

Walters interrupted: “But this is for me to say. This was sent for me, it was not sent to you.” O’Donnell: “Go ahead, you say it.” Walters: “No, I don’t want to.” O’Donnell: “You don’t want to?”

Walters ended the conversation, “I really do not want to stir up the whole Donald Trump thing again” - leaving viewers wondering what they were talking about.

Yesterday, Walters, who’s also the creator and executive producer of “The View,” was still playing peacemaker. “I am supportive of my friend and colleague Rosie,” she informed us, “but I have no desire to continue a feud with Donald Trump.”

Ratings for “The View” soared last December when O’Donnell ridiculed Trump as a “snake-oil salesman” and flopped her hair to one side in a wicked impersonation of him. Trump fired back, calling her “a fat slob” and “a bully,” and claimed Walters regretted hiring her to replace Meredith Vieira.
