As for Kim Kardashian, she was feeling more like another famous blonde. "This pic kind of reminded me of an old photo of Marilyn Monroe, with the glamorous mirror lights and the super blonde hair. I'm such a fan of hers! She is the epitome of old Hollywood glamour and femininity," Kim gushed.

Kourtney Kardashian meanwhile did not have a lot to say from the photo set but her picture in blonde wig is the clearest. A look at Kim's wig can be seen on her blog while other behind the scene photos are on Khloe's blog.
