Jensen Huang signed a woman’s chest. Yes, you read that right.

Jensen Huang is shedding his Ultimate Cool Dad status, becoming — for better or worse — the true rockstar that’s been lurking just beneath his black leather jacket.

In a crowded booth at a Taiwanese tech conference on Tuesday, the Nvidia CEO wore the same glasses and Tom Ford jacket he sported for Sunday night’s keynote address.

He signed MacBooks, chips, and even a woman’s top, just below her cleavage.

“Is that a good idea?” he asked with a smile before scrawling his name with a black pen on the woman’s white top, shown in a video posted to Threads of the encounter.

At the conference, Huang spoke about the robot revolution and Nvidia’s next-generation chip.

Huang has stayed in the spotlight as artificial intelligence pushes demand for Nvidia’s software and hardware to record levels. As the company’s stock has soared 197% over the past year, the press — has scrutinized Huang’s memo-writing style, his fashion, and his organizational style.

While other CEOs are known for their fashion, now including Mark Zuckerberg after his recent glow-up, no one is lining up with their chests out for Tim Cook.

A Nvidia spokesperson declined to comment on the signature.
