Nvidia CEO Jensen Huang allegedly had an extramarital relationship with Kimberly Powell, the company’s vice president of health care, according to a report published Wednesday by The New York Times. The newspaper cited five people who worked at Nvidia and said Powell reported directly to Huang.

Powell has worked at Nvidia since 2008 and currently oversees its health care division. According to the Times, Huang and Powell were seen acting affectionately at a hotel in San Jose, California, during Nvidia’s annual developer conference in March. Two sources familiar with the incident reportedly said the interaction was recorded on video.

The report raises questions about Nvidia’s workplace policies and potential conflicts of interest involving relationships between executives and employees who report to them. Both Huang and Powell are married to other people, according to the report.

Nvidia did not immediately respond to requests for comment, while Powell also did not respond to the Times’ inquiry. The newspaper said it based its reporting on interviews with five people who had worked at the company.

The allegations represent a separate relationship from Huang’s previously reported involvement with Alice Huang, a Singapore-based businesswoman suspected by U.S. intelligence officials of having ties to Chinese intelligence. That earlier controversy prompted Nvidia’s board to launch an independent investigation into whether the CEO had been targeted by a foreign intelligence operation.

Huang acknowledged being unfaithful to his wife in a message to employees over the weekend, apologizing to his family and colleagues. The company’s board has retained outside legal counsel to investigate the circumstances surrounding the earlier allegations.
