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.
