Joseph Gordon-Levitt has got married.

The 33-year-old actor tied the knot to his girlfriend Tasha McCauley on December 20 in a private ceremony at their Los Angeles home, PEOPLE magazine has confirmed.

The 'Dark Knight Rises' star prefers to try to keep his love-life as private as possible but he did speak about Tasha, who is the co-founder and CEO of robotics company Fellow Robots, in an interview last year in which he admitted she wasn't in ''showbusiness'' and didn't want a part of it.

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.''

This suits the actor well as he also admitted he has always had a ''phobia'' of ''getting attention from girls for [being famous]''.

Last year, while promoting his comedy-drama movie 'Don Jon', Joseph - who is a self-confessed feminist - insisted he considers true love to be a ''unique connection'' between two people rather than a ''riding off into the sunset''-type vision.

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.''
