Amy Adams -- CRUSHES Gay Bar Karaoke ... I've Got a 'Wicked' Voice


Amy Adams proved she can belt out showtunes with the best of 'em ... and by best of 'em, we mean the crowd at a gay karaoke bar in L.A. ... and TMZ has the footage.

Just days before winning the Golden Globe for Best Actress in a musical or comedy ... Adams hit up a gay bar and belted out a stellar rendition of "Defying Gravity" from "Wicked."

The performance may have been loud ... but we're told everyone in attendance was pretty impressed (and not just 'cause they were drunk.)

And now you wanna go watch "Enchanted."
