While the 33-year-old stud has yet to divulge many details about his girlfriend, the Don Jon star did confirm their relationship while speaking with Howard Stern back in September.

"I have a girlfriend, but I tend not to really like to talk about it in public," the Dark Knight Rises star said. "She is not in show business."

Although he declined to say how long they've been together, he did reveal that they met through "mutual friends."

As for why Gordon-Levitt prefers to keep his love life private?

"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," he said. "I want them to see the character, the story that I'm telling."

In fact, his ladylove prefers to remain out of the spotlight. "The girl that I'm with, she really doesn't want to be a part of it," the actor said. "You can imagine not wanting to have that kind of scrutiny."
