The 33-year-old star tied the knot with girlfriend Tasha McCauley Dec. 20 during a secret ceremony at their home, according to People.
For the most part Joseph has kept mum on his relationship with his ladylove, with the actor telling the mag back in 2013, "I have a girlfriend but I tend not to really like to talk about it in public. The girl that I'm with, she really doesn't want to be a part of that."
Tasha, who is kind of a genius, is the co-founder and CEO of Fellow Robots, a robotics company based in Silicon Valley, Calif. She also teaches a university course on "rapidly accelerating technologies," according to New York Magazine's The Cut.
Congrats to the couple!
