WWW- THE other woman in the divorce of Barbara Hearst and her infirm, elderly husband, John Randolph Hearst Jr., nicknamed Bunky, is his nurse. Sources tell PAGE SIX that documents will be presented when the divorce trial begins today in Manhattan Supreme Court showing that Bunky sought oral sex from one of his nurses.

Bunky, 71, grandson of media magnate William Randolph Hearst (on whom Orson Welles modeled the tyrannical character of Charles Foster Kane in “Citizen Kane”), allegedly asked one of his nurses, “Why won’t you give me a b- job?”

A source tells PAGE SIX, “The nurse recorded it in her notes, to protect herself. Bunky thought medical notes were confidential, but guess what? Only a doctor’s notes are. Nurse’s notes can be made public.”

The source continues, “While Barbara was out socializing and doing her charity events, it seems that Bunky was seeking a little extracurricular diversion himself. Bunky propositioned the nurse.”

Another individual with knowledge of the case says the nurse’s allegations could “make a great opening statement.”

The spouses have been separated since August, when the first whispers were heard that Barbara suspected Bunky had become attached to one of his nurses.

While Bunky’s sexual shenanigans seem sure to make headlines around the country, the divorce also promises an unprecedented inside view of the secretive Hearst Corporation’s finances.

Because Bunky is a director of the corporation, Barbara is expected to try to show that the worth of the trust and the corporation increased during their 15-year marriage and that she is entitled to a share because she took care of Bunky.

However, according to a court motion filed by Bunky’s lawyers (and reported earlier this year), Bunky’s team claims that Barbara came into the marriage with assets worth $150,000 but that by August of last year she owned real estate held solely in her name valued at $7.9 million.

Both Barbara and Bunky’s legal representatives refused to comment.
