Video - Foul Mouthed Joseph Gordon-Levitt Performs Nirvana's 'Lithium' at Seattle Benefit Show

Our favorite little actor who played Tommy Solomon on “Third Rock From the Sun” sure has grown up.

Yes indeed, he has grown up to be not only a movie star but a foul mouthed heavy rocker.

The actor was hosting the "Hit Record At The Movies With Joseph Gordon-Levitt" series at the Neptune Theater in Seattle Washington last week when he told the audience he was going to change things up a bit.

He proceeded to crank out Nirvana’s hit “Lithium” to a packed house of excited audience members.

The thing we found interesting was what a foul mouth he has as he dropped curse word after curse word.

Not that there's anything wrong with profanity...

I’m still not sure I can get used to seeing him up on a stage with a guitar acting like a musician… but props for trying.

And if this music thing doesn’t work out he can certainly fall back on his Hollywood acting career.

Gordon-Levitt can chalk up a few major blockbusters these last few years like “500 Days of Summer”, “G.I. Joe: The Rise of Cobra”, and “Inception” starring alongside Leonardo DiCaprio where he is thrown into a world where technology exists to enter the human mind through dream invasion.

And he is certainly keeping busy this summer filming the Batman action thriller “The Dark Knight Rises” with Anne Hathaway, Christian Bale, and Gary Oldman.

Joseph can also be seen this September 30th with funny man Seth Rogen in the comedy “50/50”, where Gordon-Levitt plays a guy with cancer and Rogen plays a guy who tries to cure it with a cocktail of sex, illicit drugs, and profanity.

Joseph’s budding music career really seems to be taking off and he hosts a number of original tracks on his channel that aren’t too bad.
