Jensen Huang, Nvidia chief executive who is being investigated by the FBI and his organisation over his romantic ties with a suspected Chinese spy, dated another company executive.

Mr Huang had an extra-marital relationship with Kimberly Powell, Nvidia’s healthcare vice-president, and the duo were captured on camera being cosy at a California hotel, where a company event was held, according to a report by The New York Times.

Mr Huang, 63, and Ms Powell, 48, are married to different people.

Asked for comments on his affair with Ms Powell, Mr Huang and Nvidia declined to comment.

“I don’t think you should be talking to me directly,” Mr Huang told The Times before hanging up.

Ms Powell has yet to respond to the claim that she dated her boss at Nvidia.

Mr Huang on Sunday admitted to the affair with Alice Huang, the woman that U.S. intelligence officials determined to be a spy, which caused Nvidia shares to slide about eight per cent.

Meanwhile, Nvidia and Mr Huang face a shareholder lawsuit over his infidelity.

The exposure of Mr Huang’s extra-marital affair with Alice Huang, a top executive at MegaSpeed, headquartered in Qatar, caused Nvidia to lose over $230 million in valuation.

But Ms Huang’s MegaSpeed has bought over $4 billion worth of AI chips from Nvidia.

The FBI is investigating whether Ms Huang bypassed the ban and exploited her romantic relationship with the Nvidia chief to facilitate the transfer of the chips to China.

Mr Huang admitted to the affair in a letter to company staff on Sunday.  He also apologised to his wife and children.

“I was unfaithful to my wife,” the Nvidia boss said. “My actions hurt her and our children. There is no excuse for what I did. I am deeply sorry.”

The embattled Nvidia CEO has been married to Lori for about 40 years.
