Heidi Montag, the stuck up snob from MTV's The Hills is using her success (and we use the term success very loosely here) as a reality TV star to launch a new career as a pop star.

Seems, like a good plan, right? Not if you've heard this biatch sing.

TMZ.com released a video clip of Heidi ‘performing' for a crowd at LAX nightclub in Las Vegas this past weekend - earplugs should have come with the cover charge.

Heidi's poor attempt at performing actually made Britney Spears' MTV performance look good!

Think we're joking? See for yourself.

Audience members must have been sick with fear that Heidi's flailing arms were settling past scores with those in the front row. I'm just surprised no one mistook all the onstage action for a seizure and called the medics.

Either way, I'm pretty sure therapy was needed afterwards.

Heidi's boyfriend/manager Spencer Pratt stood by the whole time encouraging her - what was he smoking? Clearly, dangerous, dangerous stuff to think anything she did up there was suitable for viewing anywhere but their bedroom.
