Joseph Gordon-Levitt has married Tasha McCauley.

The 'Dark Knight Rises' star is said to have wed Tasha - who is the co-founder and CEO of robotics company Fellow Robots - in a private ceremony at their home in Los Angeles on December 20, reports PEOPLE magazine.

The 33-year-old actor has tried to keep his romance out of the public eye but previously mentioned Tasha in an interview when he stated she has no interest in a life in the spotlight.

He said: ''I have a girlfriend but I tend not to really like to talk about it in public.

''I get up in movies and I play other people, so when the audience is watching me in movies, I don't want them thinking about me and who I'm dating, and blah blah blah.

''I want them to see the character, the story that I'm telling, you know.

''The girl that I'm with, she really doesn't want to be a part of it and you can imagine not wanting to have that kind of scrutiny.''

Joseph has also shared his views on finding true love in the past and believes it is a ''unique connection'' between two people and shouldn't be considered a ''shiny trophy'' to be gained.

He said: ''I would say true love means a genuine and unique connection between two unique individuals.

''What I think true love is not, is some shiny trophy that's the same 'riding off into the sunset' image that you can get.

''I don't think ... if you think about true love as something that you're after, that you can have, um, you're missing it.''
