Melinda French Gatesis shutting down a report that said she sought professional surveillance of estranged husband Bill Gates ahead of their split.

According to aVanity Fairstory published Monday, “two people familiar with the situation” indicated that “someone in Melinda’s circle worked with a private investigator leading up to [Melinda’s divorce] filing, which these people expect to inform both the public and private case.”

However, a spokesperson for the philanthropist, 56, shot down the claim in a statement first published in theVanity Fairpiece.

“That’s completely false,” the spokesperson tells PEOPLE. “Neither Melinda nor anyone at her direction ever hired a private investigator.”

TheVanity Fairstory — which alleges Bill, 65, was “often impatient and demanding” as a boss — comes several weeks after a spokesperson for Bill confirmed that thebillionaire Microsoft cofounder had an affair with a stafferthat took place nearly 20 years ago.

Confirmation of the infidelity came amid a swirl of reports that alleged Bill had a reputation for pursuing women who worked for him, and was known to exhibit"questionable conduct in work-related settings."

The New York Timesreported that “on at least a few occasions,” Bill made attempts to pursue women who worked for him both at Microsoft and at the Bill and Melinda Gates Foundation, which he founded with his estranged wife in 2000.

TheWall Street Journalalso reported that Bill’s past affair with a staffer was what prompted him to step down from the Microsoft board last year following an investigation — something he denied.

A source told PEOPLE last month that Melinda"was aware there were some issues"regarding her husband’s alleged indiscretions, “but it’s unclear if she knew about all of it.”

A spokesperson for Bill, meanwhile, told PEOPLE in a statement at the time that “the claim of mistreatment of employees” is false.

“It is extremely disappointing that there have been so many untruths published about the cause, the circumstances and the timeline of Bill Gates’s divorce,” the statement said. “[TheNew York Times'] characterization of his meetings with [Jeffrey] Epstein and others about philanthropy is inaccurate, including who participated. Similarly, any claim that Gates spoke of his marriage or Melinda in a disparaging manner is false. The claim of mistreatment of employees is also false. The rumors and speculation surrounding Gates’s divorce are becoming increasingly absurd, and it’s unfortunate that people who have little to no knowledge of the situation are being characterized as ‘sources.'”

On May 22, Bill waspictured in public for the first timesince he and Melinda announced their split after 27 years of marriage. Leaving a hotel in New York City, he was photographed wearing his wedding band on his left ring finger.

The couple — who share children Jennifer, 25, Rory, 22, and Phoebe, 18 — have said they willcontinue to work togetherat their foundation.
