Nvidia chief Jensen Huang is the center of a new controversy as the U.S. intelligence community believes that he had a romantic relationship with a suspected Chinese spy.

According to the Financial Times, Alice Huang, sometimes referred to as Huang Le, was a top executive at Singaporean firm Megaspeed and was reportedly romantically involved with the CEO of the world’s largest AI chip manufacturer. Notably, Jensen is currently married to his wife of 41 years, Lori Huang.

It’s unclear whether Alice Huang was recruited by the Chinese Ministry of State Security (MSS) before she joined Megaspeed or after she had already established a business relationship with Jensen, but it’s been reported that the suspected agent was apparently targeting the Nvidia head to help Chinese companies gain access to banned AI chips.

Megaspeed has been accused of smuggling $2 billion worth of AI chips into China via its subsidiary Speedmatrix, although Nvidia insists the company has no ties to China.
