Jon Heder -- Watch Me Sing Karaoke With a Hot Babe

What do you get when Napoleon Dynamite, a.k.a Jon Heder, and a really hot chick from "Spartacus" hang out at a random bar in Georgia? AN AWESOME KARAOKE SESSION. GOSH!!!

Jon and Lesley Ann-Brandt were down in Savannah with Radioactive Giant Prod. filming "Killing Winston Jones" ... when they decided to unwind at a local bar and belt out one of the most famous 90's tunes of alllll time. That's right, we're talkin' Wilson Phillips, baby.

But ya gotta check out the video for a couple MORE reasons ... one, John whips out some pretty cool "ND" dance moves ... and two, Lesley is just plain hot.
