Joseph Gordon-Levitt Dating Secret Girlfriend [VIDEO]: 'Don Jon' Star Admits to Romance He Wants to Keep Private on 'Howard Stern Show'

In a new interview on Sirius XM's The Howard Stern Show, Hollywood heartthrob Joseph Gordon-Levitt revealed that he is off the market and has a girlfriend. The 500 Days of Summer star admitted to being in a relationship but explained that he wants to keep it out of the prying eye of the media.

The 32-year-old actor stated: "I have a girlfriend but I tend not to really like to talk about it in public. She is not in show business."

Gordon-Levitt did not reveal how long the relationship has gone on. He did mention that he met this mystery girl through a mutual friend.

When asked if he was in love, the actor responded: "Oh, jeez, man! Come on! This is getting 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."

He added: "The girl that I'm with, she really doesn't want to be a part of it. You can imagine not wanting to have that kind of scrutiny."

Joseph Gordon-Levitt might not want to share any news about his love life, but he was recently very open about his lip-syncing skills. Earlier this week the young star appeared on "Late Night with Jimmy Fallon," where he took part in a lip-synching contest with the host and fellow guest Stephen Merchant.
