Smash? It's more like smoosh when it comes to Ivy Lynn, huh?  Of course we're not saying that bedding down with Derek is the only reason blondie landed the coveted Marilyn gig, but it sure had to help. After all, he did make the moves on Karen first, but Iowa was too ethical (or maybe too scared) to do her own 20th Century Fox mambo with the director to further her career.

It's a shame, really, that the sex stuff — as well as Tom's clear favoritism — had to muddy the waters of the casting choice, since both contenders are such damn fine options. Ivy has the experience, body and appeal, while Karen has the drive, innocence and a voice that can heal the sick. Now we'll never really be sure if Ivy won the role on her stage talents alone, or if Karen just needs more time in the chorus to cut her teeth. Which makes for a juicy situation for fans of the show who wanted to see one or the other to triumph. So let the diva debate begin! Are you Team Karen or Team Ivy?

Offer your take on the casting twist in the comments below and let's see who has the most support...because you never know, that role could wind up in someone else's hands before the curtain rises!
