CNBC reporter Hadley Gamble alleged her boss at the cable news network called her the ‘C-word’ — another surprise allegation that was part of the sexual-harassment complaint that led to NBCUniversal boss Jeff Shell’s shocking exit, sources told The Post.

The complaint named Patrick Allen, a former CNBC vice president and international managing editor, as the executive who directed the “C-word” slur at Gamble – and said that the exchange was witnessed by two ex-staffers at the network’s international division, the sources said.

Allen exited his role at CNBC earlier this year.

The complaint also accused another executive John Casey, the London-based president and managing director of CNBC International, of overseeing a toxic work culture within the unit.

Axios was first to report on the additional details of Gamble’s complaint.

In response to the complaint, NBCUniversal parent Comcast launched an internal investigation that culminated in Shell’s dismissal.

Shell was ousted after admitting to an “inappropriate relationship” with a coworker later identified as Gamble.

Gamble decided to file her complaint in part because she learned that her expiring contract would not be renewed, the sources added.

The contract expires this year.

Comcast said in an April 23 statement that it had “mutually agreed that Mr. Shell will depart effective immediately following the Company’s investigation led by outside counsel into a complaint of inappropriate conduct.”

The company’s statement made no mention of allegations against Allen, Casey or any other executive other than Shell.

Shell, 57, was fired for cause following Gamble’s complaint over an “inappriopriate relationship” he had with the 41-year-old anchor 11 years ago.

The abrupt exit proved costly for Shell, who forfeited vested and unvested stock options with an “estimated fair value of $43.3 million as of the termination date,” according to a company filing last week.

The company said Shell “did not receive any supplemental payments or benefits in connection with his termination.”

A representative for Gamble declined to comment.

Representatives for NBCUniversal and its parent company Comcast did not immediately return a request for comment.  

The latest revelations about Gamble’s complaint followed The Post’s report last week that the CNBC International correspondent had faced an internal probe over her relationship with another powerful figure – billionaire Trump donor Tom Barrack, 76.

Gamble’s affair with Barrack was exposed after he was caught on video loafing around in the background of a CNBC camera shot as she prepared to tape her show, “Capital Connection.”

Gamble has also been romantically linked to David Bonderman, the 80-year-old billionaire chairman of private equity firm TPG.
