More Movie Stars Becoming Singers [VIDEO] [NSFW]

Known for his acting in 3rd Rock, Inception, 10 Things I Hate About You, and more, Joseph Gordon-Levitt from the likes of such chick flicks as "10 Things I Hate About You" and a TV stint on "3rd Rock From The Sun", oh yeah, he was in "Inception" too and evidently he sings.

Check him out covering Nirvana's "Lithium" this past Tuesday in Seattle at the "Hit Record At The Movies With Joseph Gordon-Levitt."   Think he's got a future?
