Former Nvidia CEO Jensen Huang allegedly had an intimate relationship with a second employee at the semiconductor company, adding another allegation to a series of personal scandals that preceded his departure from the company, Reuters reported Thursday.

According to two people familiar with the matter, the newly reported relationship involved an Nvidia employee whose identity Reuters did not disclose. The news agency said it was unable to reach the woman for comment. Nvidia, Huang and representatives for the company's board did not respond to requests for comment.

The allegation follows reports of two other extramarital relationships. One involved Alice Huang, a former executive at Singapore-based Megaspeed whom U.S. intelligence officials suspect of being a Chinese intelligence asset. The other involved Kimberly Powell, Nvidia's vice president of healthcare, who reportedly reported directly to Jensen Huang.

Huang acknowledged being unfaithful to his wife in a November 8 statement to employees, apologizing for the harm his actions caused his family. He did not identify the women involved or provide details about the relationships.

The allegations contributed to turmoil at Nvidia and preceded Huang's resignation as CEO on Thursday. The company's board appointed Chief Financial Officer Colette Kress as interim CEO while beginning a search for a permanent successor.

Nvidia has also launched an investigation into whether Huang was targeted by a foreign intelligence operation connected to his reported relationship with Alice Huang. The company previously said its board had no reason to believe national security or Nvidia's trade secrets had been compromised.
