Former Nvidia Chief Executive Officer (CEO) Jensen Huang had an intimate relationship with a second employee at the technology company, an international news agency has reported, adding to allegations surrounding the billionaire’s personal life following his reported affairs with other women.

The news report cited anonymous sources on Thursday but did not identify the employee. Nvidia declined to comment on the allegations.

The report came a day after The New York Times (NYT) reported that Huang had a separate relationship with Kimberly Powell, Nvidia’s vice president of healthcare.

Huang resigned from the company on Thursday morning, shortly after the report emerged.

The latest allegations follow Huang’s admission on Sunday that he had been “unfaithful” to his wife, Lori Huang, through an affair with Alice Huang, an executive at data centre company Megaspeed.

United States (US) officials believe Alice Huang may be working as an asset for the Chinese government, although the allegations against her are unproven.

Huang has only acknowledged his relationship with Alice Huang and has not publicly confirmed the reports involving the two Nvidia employees.

When approached by NYT for comment on the reported relationship with Powell, Huang responded, “I don’t think you should be talking to me directly.”

The reports have also raised questions about the future of Huang’s marriage to Lori, whom he married in the mid-1980s. She has not publicly commented on the allegations.

The couple could face financial implications if they decide to divorce. California follows community property laws, under which married couples generally divide shared assets equally after a divorce.

Financial filings indicate that Jensen and Lori Huang jointly hold the former CEO’s 3.5 percent stake in Nvidia. However, it remains unclear whether they have a prenuptial or postnuptial agreement that could affect how their assets are divided.
