Kirsten Owen and Stella Tennant.

That's right.

Marc Jacobs has hopped onto the Supermodel Express and nabbed the proud mothers and former grunge icons for his Fall '08 ad campaign -- both of whom didn't take one turn on the runways last season.

As if anyone could forget, Victoria Beckham took the honors of fronting Marc's campaign for spring -- most notably dangling her super-tanned legs over a MJ shopping bag.

Suffice it to say, Stella and Kirsten have a lot to live up to. But we have faith in them -- especially since they get to play with fuzzy headbands and pastel coats that would make any Sesame Street character green with envy.
