Joseph Gordon-Levitt Is Married

Gordon-Levitt and his new wife tied the knot in a private ceremony in their home on Dec. 20, and managed to keep it out of the press for over a week – the news was first reported on Wednesday, Dec. 31.

Gordon-Levitt, 33, has been a household name since his breakout role in 3rd Rock from the Sun (1996-2001), but the actor has managed to successfully keep his love life out of the public eye. Little is known about McCauley, as she tends to stay out of the spotlight. Though Gordon-Levitt admitted he had a girlfriend during an interview with Howard Stern in September of 2013, he refused to publicize her name, and the two weren’t spotted together until May of 2014.

“The girl that I’m with, she really doesn’t want to be a part of it. You can imagine not wanting to have that kind of scrutiny,” Gordon-Levitt once said of his ladylove.

Who Is Tasha McCauley?

In fact, McCauley is far from another Hollywood girl. An accomplished academic, McCauley co-founded Fellow Robots, a robotics company based in Southern California that specializes in retail robots. She graduated with an MBA in International Business Education and Research from USC in 2013, and also holds a B.A. from Bard College and a graduate certificate in robotics from Singularity University, where she was also a faculty member.

Fluent in English, Spanish and Arabic, McCauley has said that she finds inspiration from “nature and the machine shop.” She also enjoys creating things with her hands, whether it be robots or puppets.

“Recently I made a puppet for my boyfriend. It took me way longer than I’d anticipated, but I had so much fun doing it that I didn’t feel a moment go by,” she revealed in an interview, supposedly referencing Gordon-Levitt.
