The girls of MTV's 'The City' (Tue., 10:30PM on MTV) are usually so pristene that viewers could never see them suggesting an artist wear clothing made from trashbags for a photo shoot.

But that's exactly what happened when trash-pop sensation Ke$ha showed up to Elle magazine.

Accessories editor Olivia pairs Ke$sha's leopard leotard and studded leather jacket with "trashbag shoes" or heels with trashbags on them.

Ke$ha, of course, loves the idea.

"I wanted to make a dress for the Grammys out of garbage bags but no one would let me," the singer laments.

Olivia's face in response says it all.
